With all of the Rakeback sites out there, is there a consensus on which ones are the most reliable/trustworthy?

Not sure there is quite a consensus, but there are several fairly trustworthy sites with a lot of traffic. Best idea is to find a site that offers a good promotion, such as a large freeroll or rake race. I personally use raketherake.com, and have always found them to have great service. I have signed up for multiple sites with them, and had no problems. They have several freerolls and rakeraces for most sites. Ie) full tilt right now for this month has a $20k freeroll, and $24k rake race. They are also a part of the rakeback network, which features several reliable sites, and has their own board on the 2+2 forums.

If you do choose to sign up to raketherake through as well, I would appreciate using my user ID # for referral, as it will get me a bonus as well. My # is RTR16934.

Hope this helps, and if you do have any questions about rakeback or the process, feel free to pm me.
