See what you think!
I have not yet used some facilities for example the customer review and forum facilities.This is because of the work involved in monitoring etc but i will introduce it soon ( I think..!) Again the beauty of the beast! You can be so flexible with all this..you are in control of it and can let the customers join in too.
My best to you and your endeavors

PS I actually paid Viart to incorporate the audio video preview. They have done a great job and made it very easy to manage from the admin.In the standard cart you have you can actually have a sample downloaded and i guess somehow add source code to blocks to maybe get preview..but i am not into any of that.I mean this I would really mess up!!
