Alot of great templates for Virtuemart and its MVC structure makes it excellent to override CSS and create your own look and feel.
I really hope the 3.0 for Joomla 3 is around the corner!
It is well documented and easy to setup still full of all features and extra thing you could want.
I had a little problem with my site and sent them an e-mail Just an hour later I had a guy testing it out on my website and it was my JoomSEF that made it not work a 100%. He fixed that and now its just working perfect.
I wish I could give this component 6 stars.
