i use it.
billpoint i think is better, its 2.25% only on credit cards... then again there is no "personal" billpoint.
c2it on the other hand, i dont think is as good. first off on my mbna credit card i get a 3% cash advance fee ifi use c2it to send money. apparently this is only with certain cards, but i dont get jacked 3% if i use my mbna on paypal.
paydirect just has a horrible interface and outside of that is basically the same as paypal.
so really paypal is the best out of all of them. i mean you can get ripped off on any form of payment. its part of life. do you stop using credit cards, because someone can steal yours and charge a lot of stuff on it. NO. and people who take credit cards, still accept them even if stolen ones are used, and cause chargebacks sometimes. so yeah, its the cost of doing business.
