we want to. its just that we dont have enough $$ to buy parts for 500 and then wait for them to be sold. (think about how much that is!) but what we're going to do is buy enough of the rare transistors for 500 kits (they're the only thing that can 'stop' this project) and then buy PCBs, cases, etc, for 100-200 at a time.
you can check the 'total cost' calculation (w/shipping and fees)

but you cant buy from that page.
the british/european's get a great deal, the pound/euro is so strong against the dollar, even -after- shipping and fees its like E275!
