What sites for Heads Up Play?

[Stork]

Hello, I'm a newbie to the zoo so my questions may have been answered already but I tried using the search feature and it was a complete mess.

I'm looking to deposit about $500 onto a site that offers low limit heads up holdem games. I was looking at UltimateBet, but I've heard the games there are tough. Someone suggested the Prima sites, but most heads up games they offer are no-limit, and I prefer limit, however I will do the prima sites if there aren't any other good choices.

I also want the site I sign up at to have a good deposit bonus, probably at least $100 if I'm going to deposit $500. Also, I understand it is a taboo subject here, but how should I go about getting a rake back affiliate? And if I don't have poker tracker, will they still be able to keep track of my rake?

Thanks in advance, I hope this doesn't get blown off the first page right away because I really need to know this stuff.
