We heard that the free version of Interspire Shopping Cart is pretty good. We tested it and its quite promising. The new developers did a pretty good job. We got the information on http://www.iscexperts.com/viewtopic.php?f=2&t=11 and downloaded and its been amazing. We also tested Magento but its quite slow and too expensive. We tested OSCOmmerce but there's a lot of bugs and its been outdated. Any recommendation with these 3 shopping cart software?
