Finding a miner not Made in China is like finding a brand new miner... they don't really exist.  What you can do is purchase a Made in China miner that has been refurbished in the United States by a reputable retailer who will have installed legit firmware on the machine.  It will surely be configured to point to the retailer's own mining pool out of the box, but then once it's on, just point it to Bitminter servers with your username and that's about as straight as you can shoot in the shady world of bitcoin mining.
