Tortus32,
Are you a gambling man? How long will it take you at your current rate to earn $750?
I would bet that if you paid the $750, got ccbill up and running with visa/mc, did a blitz to get a bunch of webmasters to sign up (many won't signup because of verotel), you would probably earn that back in short order. Maybe put out a request and see how many people would promote you if you got the tour leaks fixed and were using CCBill. Make the judgement at that point to figure out your return on investment.
Personally, if you are going for affiliate traffic to bring in sales, you're going to have a much harder time if you use Verotel. Make the leap. You'll thank everyone that has suggested it later.
