Ok, so I am going to bonus whore my first site. What would be my best bet for a first time deposit bonus?

-I have $500 in neteller to deposit somewhere
-I play $25 NL
-I usually 4-5 table
-I average about 10,000 hands per month
-Available to play after 10pm central time
-Use PT and PAHUD

I play lower stakes, so I am not concerned with rakeback right now, but should I be concerened with burning the rakeback bridge by signing up at a site just for the deposit bonus now?
