Looking for a running Shopp site

I have had WP Shopp on line for about 3 months ( a change over from Zen Cart ) and I have had nothing but problems with it. I’m advised ( by web site designers ) that for the size of my cart I should not have used this program because it lacks the ability to support larger carts. Before I throw away many hours of setup and adding all of our products for another program ( Magento ) I would like to see some examples. What I’m looking for are other sites that are running Shopp that I can look at and order items from it to see how well they work. Perhaps the problems I’m having are self-induced.
