I ended up going with Humboldt Bank.
I called PayQuake, but the receptionist was such a
witch (with a capitol B) I decided against using them. It was kind of funny when the (uninformed) sales guy called (almost a week later) . ;->
I also looked at Echo's offering which allows you to use the OScommerce shopping cart (hacked to their specs).
I decided against Echo after talking with a few users.
The biggest complaint I heard, was that Echo doesn't send the money to your bank. You have to use their "bank" service to withdraw the funds, and it takes forever.
Let me know how payquake goes. The price is sure good.
