It looks a bit expensive. I would rather recommend 2checkout.com over anything, any day as far as 3rd party payment processors are concerned. IMHO I don't really like the fee structure of asianpay. Don't just look at the setup fee and rather look for the long term. 2checkout has a setup fee of $49 but it's well worth. I have a good experience with 2checkout after being ripped by paysystems, hostcharge and many other 3rd party processors. One thing I like most about 2checkout is their fraud dept. which is really good at detecting fraud orders.
