DAZ Sam's 3D Renderosity are the only ones that I use the most, and maybe one or two of the others mentioned. I've never been ripped off and PayPal works just fine for me. I didn't trust it at first because I had never heard of it, but now I do and it works for those sites that don't have VeriSign or another credit card system.
