One thing to remember with pay pal: Much less international users can use pay pal, since pay pal is available for much less countries then international credit cards (like visa or mastercard). The question is: do you really want to cut yourself off from most of the world? As an international user, I have a few un-registered shareware (which I eventaully gave up on) since the only way to pay the registration was through paypal, which is not available for me. My mother is a hobby aromatherapist: again, she skipped purchasing from certain web sites since they accepted pay pal only. These are not rare examples, btw.
