can you recommend PHP shopping cart

Hi, Looking for a shopping cart. I've written plenty in the past but in Perl. I'm looking for one in PHP and I don't want to write my own. I looked at this: http://www.x-cart.com/ And I asked to see their code but I have not heard anything back. I'm already favorable to anything that uses Smarty. I'd like something that is as OO as possible. Something that's got all the core features and is then easy to extend as every customer has their uniqure requirements. Anyone got some suggestions?
