Hey, I buy proxies from these guys...in my experience they've been pretty awesome...
The list I'm using right now is located here:

...but they pretty regularly put up free sample lists.
IF you like this list, I <b>STRONGLY</b> reccomend buying some. They're cheap as hell, and are excellent. Nice uptime as well.
If you want em, get in contact here:

...leave them some contact info. Out of the admins, I'd reccomend talking to whichever one is not rel4x, he gives the best prices.
