It sounds like you want to start mining smaller amounts until your rig gets in. Maybe to practice or something?
I know people on Reddit sell USB miners all the time.
http://www.reddit.com/r/bitmarketThanks. I'll look into that. Yeah I'm wanting to try a couple of things out before they get here to better optimize them. It's much harder to turn a profit really unless you start with a lot to invest something I don't have when doing SAH-256 but even though the cheaper route and better long term mining would be in script mining since there isn't any big Hash chip makers for script yet to saturate that end so it is easier to get into and the rig last longer before needing to up it, but to build one still takes quite a bit.
Eh, as long as you break even! Whenever I mine any coin I just look to break even and have fun mining and supporting the system. Also, if you want to, try mining a alt currency just to get SOME kind of coin. Might make it more fun while you wait for your BTC stuff to arrive!
