GameFly
GameFly has been pretty good - Gamefly.com

I admittedly don't go through games too quickly, so maybe I'm not the best judge of how quickly they get games out the door - but I can say that I tried Gamemine, which is cheaper, before I went to GameFly. Sure, GameFly isn't INSTANT... Sometimes I put one game in my queue and wait a week or two... It's worth it though so I can keep a brand new game for a month or two. On the other hand Gamemine was horrible - even with 5 or so games in my queue I would get nothing for weeks.
