So far I believe Spondoolies-Tech is one of if not the best miner manufacturer there is...unfortunately the price is still high enough that it will make 50% of what it costs before it's useless.  I was going to buy the one at Inside Bitcoin NYC off the table when I realized, it's a great machine but with the dropping price of Bitcoin nothing available now will ever make more than 50% of what's paid for it. 

Spondoolies-Tech is on the right track but $3.60/GH will only break even or ROI if BTC goes to over $1,000 a coin.
