I have had half a dozen people already express interest in buying a kit, and only in the first few days. 

The playfield is heavy, but with one other person I got it out and it was heavy, but not to the point we couldnt easily carry it. The cost to design and make one proto-type will be less than $150 at the very outside top cost, perhaps even half that. Dont ya find working on a playfield in a cabinet very restrictive. On a rotisserie, it is a breeze.

I just find lifting a playfield up n down fifty times is painfull, espescially when u are trying lots n lots of different LED's etc compared to standard bulbs.

I think the kit will be a winner. I will update the post when Beaky (Andy) and I are a little closer to finishing the first proto-type.
