i play mostly 2/4nl and 3/6nl. i'm beating them for a pretty decent rate too i might add.

but then i see players like pooruser and others just destroy them. they end up with huge stacks on multiple tables. i would really like to advance my game and learn from the best.

A little offtopic, but PoorUser actually offers tutoring on www.liquidpoker.net, and there are plenty of other good players that offer tutoring there and elsewhere. If it's just videos you're looking for you can't go wrong with cardrunners, sbrugby's videos in particularly are great.
