Quoted from pezpunk:eh, nobody is going to be able to build and sell a new Taxi for $2k. Probably not less than $4k without going bankrupt (i'd love to be proven wrong). too much labor and shipping cost and overhead built into the process no matter how simple the pin is. could you even run the playfield, manufacture all the parts, package and ship them to the customer totally unassembled for $2k? i doubt it.
I think you have hit on a great idea here...an assemble yourself pinball kit! In a market filled with DIY, build clubs, and the like, I think there may be a niche market for this idea to work!
At the very least...i would be into building my own pinball via putting together packaged parts and following a build guide/tutorial.
