WordPress eStore Plugin

Has anyone used the WordPress eStore plugin? It looks like a nice plugin for selling digital products on WordPress sites, and the price is reasonable.

If anyone has tried it, I'd like to hear some opinions.

No one has used this plugin? :confused:

Thus far, the only issue I've found is that the plugin does not deal with local state or province taxes. However, I contacted the plugin authors and it looks like they will add that to the next version.
