Those early Korean sets aren't bad at all. They were fairly well built, and once the tech got familiar with the Korean design, not too hard to work on. Celeb-ownership value? Not sure. I've had sets belonging to various celebrities, and unfortunately, it didn't seem to do anything for the value here in the Los Angeles area... Martha Raye's CTC-40, astronaut Buzz Aldrin's sets; Sylvania 19" and RCA 15" tube set), and I also had a Panasonic projection set which was completely thrown out of alignment by Vince Neil (Motley Crue), and a Sony LV-1901 TV-Betamax console which belonged to Ringo Starr and Barbara Bach, even President Reagan's cheapie RCA VCR from his Century City office after he left the White House. Sadly, I think all of them wound up dumped, except for the LV-1901 which now belongs to another SoCal TV collector, and the Reagan VCR may still be on a shelf with an inch of dust on it down in West LA.
But if celeb-owned sets become more of interest, I have a whole housefull of sets that presently belong to a 1990s actress who did season 8 of Seinfeld, and other stuff in the late 90s....
