I did say 20 if everything is new, except engine. Scrounging costs time, lots of effort, and you have to have cash any second a deal that moves your project forward comes by. A $2000-3000 project is like getting $10000 worth of materials and time. A $10,000 plane will not have new grove gear with fancy wheels and brakes, you will be making the cowl and wheel pants, pretty much nothing prefab. Solving problems means the builder solves them.
