It would be a very risky investment, pretty or not. If you can get something close to that from Cessna, say, then you would be looking at a lot less risk when it came to getting your money back.
Another thing: A big company such as Cessna has so much more depth to its engineering and support. Imagine you are grounded someplace far, far away, when you need a knurled flange bracket "yesterday." Who are you going to want to call for that, the big company, or a tiny one?
