Yes, fulltiltpoker is a good poker site. You may also take a visit at TitanPoker, 888Poker, PartyPoker and SportsBook. Along with FullTiltPoker, those are five of the best to play poker. It depends on your choice on what suites your taste.
I mostly play on Full Tilt Poker and PokerStars. I play Guaranteed Poker Tournaments at Rockem Poker or Poker4Ever which are on The Everleaf Network because the tournaments have high overlay.
