Played on PS a few years ago for a while. Right when UIGEA hit, my debit card stopped working there. I switched to FTP then and have stayed.
I currently play tourneys no larger than the $6.50 superturbo ko (unless I'm drunk), and I usually am staying with $3.30 and under. My most profitable tourney by far are the $3.30 90 man turbo ko's (around a 70% roi through about 250 of them, I think).
