To each his own - it is a hobby. A lot of people do things I don't understand, whether it has to do with airplanes or not. If they are enjoying life, that is what matters.
Airplanes I care about get components I believe in. Throw-around planes get whatever it takes to get them to fly. I prefer to have a small fleet of nice planes with quality parts.
Obviously this is turning into a debate of whether or not the name brands are worth the extra price. Everyone has different values. My values steer me toward the name brands.
