I guess this is the best alternative to paypal.

I am going to look into it a little more myself and maybe try it. I don't trust paypal, never have - I've heard too many legitimate horror stories. Unfortunatley there isn't another 'ebay' out there right now. I use it to try to get rid of stuff from my hobbies here and there and other odds and ends. The hobby stuff I have been able to use the hobby related websites but not the other 'junk'.
I have never accepted anything but checks or money orders and I haven't had a problem but I am also small time in that I only have about 100 sales transactions.
