I'll give another nod to MonoPrice. For longer runs (35-50ft) I would reccomend the 22awg, for everything else the 24awg/26awg/28awg is fine. I would stay away from "equalizers/extenders" as I've had bad luck with them and had a better signal using just 50ft of 24awg. I also really like the color-coded 28awg for short patched of multiple sources into one switch/receiver. I have 3 sources going into my Pioneer Elite 82TXs... I use Blue for BluRay, Red for HD-DVD, and Green for Tivo. Very helpful at the receiver end to easily identify which cable goes back to which source.
