So seems like my deal will go through with them, but they wont be able to send out my shipment until the first week of feb. As soon as I have the final numbers per unit and the freight shipping cost from them ill open up another thread for a group buy-in. It will most likely be conducted in a similar fashion to my USB scrypt stick pre order (except you wont have to wait months for these Wink

. All BTC will be pooled in a public address that I will send directly to bitmain, they'll pallet drop ship all the units to me in NY, and ill simply slap a shipment label on them and send them out to you guys.

I know some of you guys have PMed me already, but ill start putting a serious list together with the number of units you guys are interested in so if you haven't already shoot me a PM with the number you want (figure around $1600 each unit).

Seems you are quite knowledgeable on those units, have you already calculated ROI with increasing difficulties & stuff and can give us an approximation of the true ROI ? i find it hard to calculate for ASIC based miners, i use this calc : https://bitcoinwisdom.com/litecoin/calculator, with 1% increased difficulty, but aside if you don't pay for electricity you don't seems to get ROI like ever and even it take 2+ years. So am i doing it wrong or is there some sort of secret to find those device to be profitable, like only doing alt-coin ? I was told this calc may not be accurate either. What do you think ?

I wish I could say I am a fan of Bitmain products... But that would be a lie. Having owned the A4's before jumping into the L3's I can say that the build quality seems to be better on the A4's. Inno did a good job and appeared to use rugged well made stuff to build their miners. They are heavy, and ruggedly made. Even the heat sinks on the boards are massive. After that experience with the A4 you have an expectation of something similar with the L3 miner, but it isn't built nearly as ruggedly as the A4 sadly.

So far I love the L3.

Thanks for your review man

the best ROI calculator will be what Jstefanop posted earlier in the thread, as, as he stated also at the same time, https://bitcoinwisdom.com/litecoin/calculator is still using 50LTC as a block reward ;p
https://www.cryptocompare.com/mining/calculator/ltc?HashingPower=250&HashingUnit=MH%2Fs&PowerConsumption=400&CostPerkWh=.01

keep in mind theres alot of variables, but the bottom line IMO is : Mining is a long game now, EXPECT a year+ ROI unless you have "free" power ;p
