mp3 shop solutions

I don't like to pay money for selling my mp3s / movies online

are there free shop solutions for selling downloads?

I saw ochre doing it with paypal but you obviously need a script that the mp3 can not be downloaded without paying

any suggestions? what are your experiences?

I use a paid-for script for WATMM Digital Downloads that works with PayPal, but here's a free one I found that looks pretty good:

this looks nice thanks a lot

whats the paid one called you use and what are the advantages?

Are there any services that i could get some libraries for instead?

Simply put:

1) Do not want PayPal, want to accept credit cards.

2) Want to pay a percentage of sale; no recurring monthly fees.

3) I write my own PHP code, and I'd just want a library to handle the financial shit... that is, ChargeVisa(amount, num) as opposed to YOUR COMPLETE E-SOULTION

Thanks.
