I used to be rabidly anti-DRM, but my mindset has mellowed somewhat and is similar to your's now. When I'm buying a game for $5 in a steam sale, more often than not it is a game I'm not likely to ever replay. Same with digital purchases on XBL. The games I know I'll replay (Baldur's Gate, IWD, Mass Effect, etc) I have physical discs for or have purchased through GOG.
DRM is perfectly fine for something you only want to play once and can get at rental prices.
