Hey all

I'm looking for a shopping cart which will allow me to add nearly 10,000 products under several categories. I've narrowed it down to four choices and was wondering if any of you have had any experience (good or bad) with these carts. They all seem to be pretty popular.

DigiShop - http://digishop.sumeffect.com
X-Cart - http://www.x-cart.com
SquirrelCart - http://www.squirrelcart.com
Turn Key Web Tools - http://www.turnkeywebtools.com

Your experiences and opinions would be greatly appreciated
