2checkout can get pretty pricey and more customers will want to use paypal over to checkout. belows a breakdown of there fees, i made this example for a hosting company who has 500 clients paying $6 ea per month.
2 Checkout:
($6 x 5.5%) + .45 = $0.78
$0.78 x 500 = $390 in fees per month
PayPal:
($6 x 2.9%) + .30 = $0.47
$0.78 x 500 = $235 in fees per month
Customer support quality is about the same for each, none
