Excellent point......... I say we ask Rod to pin new numbers into the old price guide!
I say we ask Moondawg to start a column for original machines.
I know you refurbish the good ones and keep them original and I thought you did a lot of that for your shop. Rustmort, polish, cleaned and maybe rewired for the end user sale of a cooling working machine.... You have a good pulse of what the retail asking prices are for the originals and won't undervalue them. The book price for an original is for a crappy paint, wife will kick you out for bringing it in the house, might be missing parts but can be found, and if I recall, may or may not cool!
R-12 isn't $9.99 at napa anymore, we all know cooling is a $3-600 swing in price right there because it scares lots of people off. (especially from a retail perspective because its a project not retail value)
