Suggestion on a good php E-Commerce software?

Hiya hey!

I’m trying to find a piece of software that’s written in php - an e-commerce thing. I found many, but most don’t have all that i need:
[]template changing system so I can skin it.
]allows credit card and **paypal **as a method of payment (which would also include support for 64-bit servers etc). Now, this doesn’t have to include cc# varification, it can involve a 3rd party company that processes this, which can be a plug-in. Doesn’t matter - as long as they work.
[]easy customer tracking and stuff, since I won’t be the owner of the shopping site.
]written in php - so that I can modify it :slight_smile:
[/list] All of those would be great, and essential.

Thanks in Advance :beard:
