Have You Bought a Used Homebuilt?

For an upcoming article, I'm looking for pilots who've purchased any of
the following completed (already flying) homebuilts from previous
builders:

Van's RV-4
Glasair II
Lancair 320/360
Zenith Zodiac (CH 601, 601 HDS, XL)
Avid MK IV
Kitfox Model IV/Classic IV

Specifically, the topic is particular items of importance to look at on
these airplanes if you're considering purchase of a used one. If you'd
be willing to talk about your story, please reply with e-mail address
and/or phone number.

Thanks...
