My advice would be to use Stripe.com for processing payments. You'll be
amazed at how easy it is to get started AND customers don't have to leave
your site!
(I'm not associated with Stripe in any way... just using it with App Engine
and can attest to its ease of use)
I may re-add PayPal at some point (in addition to Stripe) but it's a pita
to deal with the user leaving your site, processing the ipn notifications,
and then HOPING the user hits the button to return to your site when he's
finished on PayPal. With PayPal there's no guarantee the user will return
to your site (although it's fairly likely). I've also noticed that the
initial redirect to PayPal can take a while (for the page to load). Just
my experience... I'm sure there are others that really like it.
