$500 bankroll: Where to next?

[Sampson26]

I started my bankroll at UB and cleared my approximately $70 bonus and just cashed out with $500 after some grinding and running hot.

I am at an impasse now, since i want to move up limits to .25/.50 (NL) but the only action at UB are jackpot tables with an extra 50 cents taken out of each hand. So i obviously need a new site(s).

Basically as an American what are my best options for quality and quantity of games and bonuses, and is it best to spread the 500 on a few different rooms.

The full tilt 100% bonus looks attractive, but is it realistic to earn 500 through it playing a mix of .10/.25 and .25/.50? Thanks in advance for any advice you guys might have.
