Stan James Poker have a decent selection of tournaments; daily freerolls, big Guarantees, Qualification packages, and simple old freezeout and rebuy tournaments.
The biggest tournament is the monthly $250,000 Guaranteed, held at 18:30 GMT on the first Sunday of each month. The buyin to this event is $150 + $15., though you can qualify through satellites for $10 + $1.
The biggest weekly tournament is the $175K Guaranteed held on Sunday at 18:30 (if $250K event isn't running). This buyin is $60 + $6, though you can qualify from $5 + $0.50.
There are also daily $1000 freerolls running to help you build up your bankroll for no extra cost.
The best tournament for playability is the extreme stack $50K Guaranteed on Saturday (18:00 GMT). The buyin is $100 + $9 and you receive 5,000 starting chips. This tournament is great if you like deep stack events. Satellites also run for this event from $10 + $1.
The Sit and Go (SNG) games at Stan James Poker are popular too. The games range from the micro 9c + 1c to $750 + $65. Unfortunately you only receive 1,000 in starting chips as standard.
They also run the "rounders" promotion whereby if you win your SNG you move on to the next level, up to level 5 - which by that time could have seen you turn $5 into a first prize of $3,000. See site for further details.
