Vary nice execution.
Did you build a custom template for the product page like Nifty Product Tutorial http://www.ubercart.org/forum/development/3868/nifty_products_tutorial_p... ?
If so how did you add the Add your own review (code wise)
Also I noticed when I click the add review link on http://www.transformetrics.com/products/isometric-power-revolution at the top of the review form is says

Add your own review Even though there are reviews on this item already.
Once again very nice site.
