thanks for all your input.

Is there anyone who tired this and would like to share some info?

Well I've got 730mh of KNC Titans (roi'd) and make now on LTC after 14c elec at 3000 watts the amount below at 3.72 per LTC

30 days 220.81359375 LTC 821.40 USD Total 302.40 USD Electric Costs 519.00 USD Profit

using the below free calc for LTC which allows to change all values...kinda nice..no fee pool pays 104% ....

www.litecoinpool.org/calc

So I recently split a 2 Titan system buy it now on Ebay for 3,500 usd and 150 shipping...(its supposedly in the mail it may be a box of rocks)

So for that investment (nice Unicorn hunt imho ...the price SEEMS right) of with shipping $1,825 usd

But then I made the mistake of looking in to the figures on this toy ..and my elec prices (argh summer heat) and how things kinda have to break my way for it to ROI....

I get the below with the above calculator for this new titan unit at 300mh (add this to the above for my total hash rate of say about 1000 mh if/when it comes and if it works?)

So 300mh at 1200 watts (gen tarkin firmware cuts it down a bit) at 14c kwh and 3.72 usd per LTC I get the below on that unit

(considerably underpriced from what I can tell from Ebay ones going for 3k plus)

30 days 90.74531250 LTC 337.56 USD Total 120.96 USD Electric Costs 216.60 USD Profit

So if the above is in the ball park....and I take the profits after Electric..it would take me AT THE CURRENT DIFFICULTY about 8.4256 MONTHS....add some MODEST

difficulty rises and say 10 months....

hmmmmmm.....

IN that the A4 400mh Scrypt Miner is supposed to come out in July...and I would suspect a corresponding data hall by them and bulk sales....

I MIGHT ROI on this before it all goes doorstops

then again....IF the Innsilicon folk dump a lot of chips on the market for bulk sales (hey it is what they do) and A4 equipment and the price does not do much

more then say 4-5 bucks for LTC...er ...I still may ROI but would be kinda like paying LTC running in circle for 10-12 months to get back to what I put in for LTC.

The point I'm making is the ABOVE IS A GREAT PRICE for a 'supposedly' NEW Titan Nov 2013 unused unit......assuming you can get 300mh out of it (gotta love paypal

as a backstop and the cc ....just need something near 300mh and I'll keep it)

But UNLESS there is say a pretty large price hike for LTC as compared to BTC (which has its own issues on difficulty rise etc etc) say something like if BTC hits 650 usd
then at a kinda current LTC ratio of 0.008 ltc to btc it is now ..that is $5.20 LTC...

but ..again the higher the price the more OLD equip gets turned back on and the higher difficulty climbs

anwyay ...my point is I will likely make ROI on this because PRICE of LTC connected to BTC will got up....but even then the likely REAL $$$ I will make is when in Oct 2016

my elec rates go down from 14c to 10c a kwh and I heat my house on the 4000 watts of Titans (hey did it last year on 3000 watts)

So to wrap it up...even at that really good price above ...at my elec rates....even adjusted for next winter..and the rest...other considerations have to come into play

its a hobby/ i get heat in winter out of it by extending out the equipment/ reduced elec rate/ possible price hike in BTC and also LTC

but if you look at the above 'realistically' and I had NO Titans at all now.....running the numbers...with all the above you'd be better off just buying BTC and holding

so hey ...its a toy ....that LIKELY will ROI in some combo of the above manner

AS to Ethereum mining till it goes POS coin....from what I've been told... you can get more or less per GPU the same kinda/sorta return on 1 GPU as 1 Titan Cube
with probably more then a bit more electric use? not sure....

So you could play my game above with GPU cards and ethereum even at the 7.50 ethereum usd prices etc.....if you hold it could moon I guess

if you go from Ethereum to BTC direct ...it probably for the next say 5-6 months be little different then my Titan bet etc and you can use/sell the gpu's later

But the 2 examples above are the only way I see home mining anymore.....if you ROI etc is up to a lot of chance with 'tricks' above....

me ...I'm just postponing the inevitable...by adding to equip I've already ROI'd on as a 'bet' price/winter rates and heat of house will pull me out to ROI on this new stuff

i mean 'really' increase my hash rate by 1/3 for 1,825 usd added to equip I already have...sure ..I'll take that bet in that I've already drunk the kool aid and got equip

setup for such...same for a lot of guys I know who rushed back to the family farm and dug the gpu rigs out of boxes in a shed.....yelling whooo who...

It is all great fun....but at this point in time if you are NOT in to this stuff and can walk away with a smile when it all 'bricks' itself and say 'fun toy'

you are imho better off just getting some BTC or LTC for the anticipated (year after) hopeful 'pump' in price.....same results...a lot less dorking about
