Monthly rakeback amounts

[ThE_DrOpOuT]

Can anybody that plays on a site that offers rakeback please fill me in on what they are making in a month. I am debating which site to sign up for a rakeback deal with and any advise would be much appreciated. Fwiw im leaning towards sun poker because they offer up to 50% rakeback for anything over 5500 raked hands in a month, and according to a rake calculator if i play 30h/day, 4 tabling at 1/2 limit i can expect to make about $2300/month in rakeback. This seems almost too good to be true and probably is, but if i can just play break even poker i will be way ahead in the long run.
