Re-Deposit Bonus Question

[GeoffM]

Hey all, I think I have pretty much a complete library of poker accounts on my computer now, thanks to none other than TP. My question is: Which sites and how often are the re-deposit bonuses?

It appears as though UB has once in a while, but tough bonus to clear. Party seems to have one every month, but other than that, which sites have re-deposit bonuses and how often are they?
