Cinemanow

Cinemanow is an awesome source of LEGAL movie downloads at reasonable prices. Because really, the "free" part of P2P downloading is misleading, considering the risk of both legal action and craptastic quality.

Cinemanow is still working on their marketing, but I happen to know that you don't have to subscribe in order to download movies, you can just do PPV. The categorization is sensible, and the selection is excellent and growing all the time. Really excellent stash of indie, foreign, and otherwise hard-to-find films, besides the major releases.
