Personal preference--some folks just aren't inclinded to build but they don't want a 40 year old airplane either. My original quote assumed that the OP wanted to build. The age old addage is if you want to build, build, if you want to fly, buy. Looking to build as a cheap way to get into ownership is fraut with fautly logic IMO. Sure, when comparing a new E-AB to a new factory built of similar capability and performance, the E-AB can be significantly cheaper, but only if you discount the opportunity costs associated with building. Folks buy used E-AB because they want something that the Piper's, Cessna's, Mooney's, etc of the world can't provide. For a used aircraft like an RV, determining the quality of the build and it's airworthiness is no different than a Cessna. A rivets a rivet regardless of who set it. Any A&P can look at an RV and provide an assessement. Now move into the glass world and I'm more inclined to agree with you, yet Lancairs and Glasairs change hands all the time. I think in the case of glass, it's more importrant to get the aircraft inspected by an expert on the model and conrtruction techniques used rather than just any old A&P.
