At least in the case of the 690 series sets, because they are a console, and a big one, and not as recognizable with a somewhat nondescript dial , that limits the market more. Unlike the Brand Z Walton sets there is something going for a 690 other then the cabinet style, or that one it's siblings was an anachronistic TV prop. Even in the case of the Brand Z I think that the prices may have got too out of hand even for loyal followers of the "Order of the Big Black Dial", at one point they were getting up to $3K for them. Like with the catalin sets too many of the unscrupulous money guys got into it and started souring the market with Frankenradios and bastardized "restoration" jobs.
