Carbon poker

From what I have heard, Carbon is a good site.  The layout is good and so is their support.  It's main disadvantage at the moment is from a lack of traffic, which can be a good thing with regards to overlays on guarenteed MTTs. 

If you do sign up, you need to sign up through a rakeback affiliate to make sure you are eligible to receive rakeback.   Most rakeback sites will offer ~30% for Carbon. 

If you don't plan on playing there very long, you may wish to use a kickback affiliate and get an additional bonus, which, when combined with the first deposit bonus can make for a quick bankroll boost.

Hope this helps.  Feel free to pm me with more questions or if you would like a rakeback referral link,
