Yes, it is a easily skinable script. I'll check my old bookmarks and see if I can get you some links to people who skin this cart, for examples...

Check out this site for a few http://www.sherbetlemon.co.uk/shop/index.php

There are others, and you can comment out sections of PHP for the features you don't need.

Additionally it's free, unless you want to remove the copywrite at the bottom, then you have to pay the 69.95 license or whatever it's current cost is. I think it's even available as a fantastico script if you have cpanel hosting.
