I went to eBay and took a look. Units that were in great cosmetic shape, working, but had not been rebuilt, were around about $900 to $1300. Professionally refurbished ran from about $1300, up to $2200. Ones that looked like they’d had a lifetime of ordinary use and care ranged from $300 up to that $800/900 figure. These were realized prices from completed auctions, not asking prices.Hope this helps.
