If I want a quick-and-dirty prototype or breakout board and I don't mind waiting 2-3 weeks, I use dirtypcbs.com. Always good quality and crazy cheap. If I want full-up assembled prototypes I use macrofab.com. I can usually get fully assembled prototypes to my door in ~3 weeks for $30-$100/unit. Manufacturing and assembly is so cheap now I don't even bother doing any of it at home anymore and only keep a small stash of parts for troubleshooting/debug in the home lab.
