The Best Shopping Cart Plugin

I've been looking around the past couple of days and keep comming back to the Shop plugin. from shopplugin.net It looks like it's user friendly, everything is laid out easily, and very customizable?

Before I buy it I wanted to see if anyone has any comments on it or possibly a better recommendation?

Have you looked at ShopperPress?

It's pretty awesome and there are lots of coupons floating around online.

Try SimpleCart &CraftyCart too.

Take a look at phpurchase too. Before you buy any of them look for coupon codes, you can get 10-20% off from the prices.

And on the forum you can find eStore theme from elegantthemes for free as well.

Thanks for the replies guys, I actually just went with wp-ecommerce for right now, but I'm looking at some others to try testing out on some other commerce sites I'm working on.

On a side note, do you guys happen to know whether or not these carts allow me to add products with posts and categorize them with categories? or is it like wp-ecommerce where the products are added through the plugin? I'm kind of disappointed with wp-ecommerce because of this aspect, I'm not able to edit and add stuff to the pages through custom fields and short codes.
