The high price must be mainly due to liability issues and paperwork because these things cost around 150$/Euros/GBP for homebuilt aircraft. Which is still 100 times the cost of the parts... But otherwise I fully agree with you, keep it as simple as possible. The pneumatic stall warner of the Cessnas is very realiable - in my experience a lot more than the electric ones in Pipers for example. And really, whats the big deal in putting a piece of cloth over it and just testing it?
