I play there occasionaly when I want to play and not risk any
bankroll. The competition is much better than at the play money tables or the
freerolls on other sites.
There is also another site called Spade Club that has the same kind of setup i.e. a monthly fee and unlimited play with a chance for cash payouts.
ClubWPT also has a tourney where you can win a seat on a televised final table with a larger payout 5K I think.
