I also use Paypal to accept direct purchases from the Netherworks Studios site. Honestly, it's the most flexible (considering the number of countries it covers worldwide) and cost effective solution that I've found thus far. As far as getting your downloads and so forth... that all depends on how that website has its store set up and Paypal only functions as a front-end (to the best of my knowledge) for that. For example, at Netherworks, we use Paypal's cart function so that you can convieniently shop and the purchases show up in a separate window.
