I play the 200-400 games at PArty and Full Tilt. I get stacked once every 350 hands or so I'd say. Usually this is because I sometimes push with draws and/or me making a genius or stupid call when i think someone's on a FD.

I'm also on a ridiculous dowswing, so maybe I'm getting stacked more often than I should. (right now getting 3 outered feels good).
