I'd say it depends upon what you like to play (ie. I mean like > sng's, MTT's, cashgame, etc.).
There's a couple of 'non' US sites that I play on that are decent for some games (w bankroll of that size)... but the bonus isn't easy to clear at all.
888Poker has soft micro cashtables (especially for anyone playing 2nl.. prob cuz of the 'free $8' they hand out there). THey have quite a few $10-$20 mtt's as well, with ~150-500 entrants. Software is ok... but takes a bit of getting used to. Also, the tables size differently than Stars & FTP so it's a bit difficult to fit them in on screen if multi-tabling MTTs.
TitanPoker is another 'non'US site that is decent/ok for the low buyin MTT player. They don't have a ton of Tourneys in their lobby but there are a handful of ones $5-$30 range, with the $20-$30 mtts having decent structure (ie. there's a $30+3 where you have a 6,000chip starting stack, ~110-130 entrants, top20pd). Couple of decent rebuys on there too, $5 & $10 with $10k-$20k guar. prizepools). Titan is another site (running on ipoker network) that has tournaments with small sized fields than the big sites but still has enough traffic that for tournaments. SNG play is less than desirable imo, ie. if you're playing the 30plyr ones ($5-$10) chances are you won't be able to play more than 3 at a time at any given time during the day (maybe 4 at tops).
OP, 'it depends' on what you're looking for in a site (aside from deposit bonuses). List some of the things you're looking for & I'm sure you'll get a bigger response on here.
