tommaso bikes
 

how much are their Al. frames worth? I saw a good deal on one of their bikes and wanted to strip them for parts and sell the frame?

Price the components individually at their cheapest online, subtract that sum from the price of the assembled bike. I don't think the frames are any more special than a Nashbar frame or any of the BD frames, but I have no practical experience other than bikes at that price point all using the same business model.
