Best commercially available examples of TK-41 color?

Tough question, most shows from that era were shot on film, the ones that's weren't, like the Evening with Fred Astaire or Dinah Shore aren't on DVD, at least not in their color videotape versions.
Variety shows are hard to get on Home Video, probably because of copyright issues.

I think the 1960 version of Peter Pan is on DVD though, I think it was shot with a TK-41.
