Zen Cart as a ecommerce solution to sell digital files

I've been looking at a lot of different solutions to use for e-commerce and there aren't a lot of options that work, especially for digital files. I tried Wordpress with an e-commerce plugin but the plugin was buggy. I looked at different hosted options specifically for selling digital files and found that the cut they took for selling was very expensive. Then I setup a Zen Cart install, which is a one click setup thanks to DreamHost, and it worked great. There are very good setup instructions for selling digital files provided by Zen Cart. Zen Cart has a lot of bonuses that one wouldn't expect from an e-commerce solution like newsletter management and a CMS feel management.
