how good of hash-rates do I get though? Is it comparable at least to a GPU or a few GPU's (if a have a few USB miners running?) Whats your feedback?
Anyone know a good deal of where to get them as well?
The only USB Scrypt miners I have seen are the "Scriptor Solo" FPGA from http://ltcgear.com/, those only hash at like 25-45kH/s each. I thought about buying some back when they were in-stock last year. It might not seem like a lot of speed but the low power cost is nice.
Alternatively you might just want to check into Cloud Mining which can be a little expensive, but then you don't have to buy any hardware.
