On rakeback: Yes, what Wobbler said is exactly what I meant. My favorite site to play at (when I'm not earning bonuses) is UB, however I can't get rakeback there because I signed up with them before I even knew it existed. Result: only play I make on UB is tournaments, where the rake is minimal.

Also, for the record...Technically, a $100 bankroll is rather small for NL$10. Usually it's recommended that you have as close to 30 buyins as possible, so I'd look for at least $200, up to $300, when moving up.

Once you get up to $100, however, you will be properly bankrolled for $5 SnGs (assuming 20 buyins is enough for you to feel comfortable). If you do well, the next $100 will come a lot faster than the $50 you make to get you to that point.
