Stop giving the guy a hard time. He is NOT a manufacturer but clearly a reseller. If anyone thinks they are a scam, simply do not buy from them, period. I am sure their prices will put off a lot of people, as the very same rigs can be got from the manufacturers cheaper (albeit subject to taxes).
But honestly, would any "respected" member of this forum asking for a rig to be sent before paying actually pay for it if it were sent (at their prices)? The answer will be a convoluted one, arguing price point, shipping et al and ending with NO. So why do you ask if you know you can not (and will not) pay for it? Cut the guy some slack.

Well it seems we're past the 300 point, so I'll start:  +3.01 to +3.25%

in 40 days S5 produces just ~$130 minus electricity (has to be at least $18.48 if the cost is 3c/kwh), so no more than $110 produced.
It could pad the margins, though.

As per subject.
Looking for mining options to use come fall. I have cheap power($0.08 USD/KWH). Previously I was able to heat my home cheaper by mining than with the actual heaters in my friggin house. For the first winter I even made a hefty profit and kept the home nice and toasty but since GPU mining is more or less dead I sold off most of my gear. Whats out there these days that I should look into?
I'll probably fund the purchase using BTCJam so cost isn't an issue assuming the device actually has potential for a decent return.

what if s7 will come out ~December!

I would arbitrarily define individual as anybody with less than 0.1PH (100TH)=~100 S5 or ~20 Sp30-35. If you have more-you are a real business.
My prediction is not more than 10-15%, but I could be wrong and would appreciate pointers to an accurate estimate.
How many SP30-35 were produced? I remember seeing $28mil revenue for Spond.
With an average price of probably ~$4000 over lifetime of sales, this would be ~7000 machines or ~30 PH. Maybe 1/3 are individuals or 10PH.
Phil was posting estimate of S5 sales somewhere, but I could not locate it.
Antpool has ~20% (~80PH), but it is not necessarily all S5. Maybe 1/3-1/2 are individuals=26-40 PH or ~20K-33K machines which looks like an overestimate, so perhaps these numbers are too high. If estimates are correct, then ~36-50 PH are individuals (9-13% of the total hash) without counting S3.
Opinions?

I think your best bet is to find a cheap S3 around $80 and start mining with that.  It's a lot more profitable than a usb stick miner. 

If you are set on a stick miner than sidehack has a really good device coming out you can grab and mess around with

If you started any time during the last 167% of the 666.666% block, then you will be on target of 100% (or better the later you started) for 4 blocks already.
So yeah that just depends on the next block if you hit the 100% for 5 blocks and the expected average payout.

Also, the average fee was quite good on those 4 so the PPS on them (again if you started mining during the last 167% of the 666.666% block) should be ~99.95% after removing the pool fee.

Waiting for real world numbers

I don't think 5% is a shocking number especially for a new style of hardware that is running 24/7 (these mines never ever turn those things off) I mean just look at major hardware companies and they have a similar death rate and those things are turned off commonly.
