I have a GE 1VCR4002X from 1983 and a Sanyo Betacord VCR 4500. The GE my parents got me from the Thrifty Shopper a few years ago. It came with the original owners manual and two, count 'em,
two wired remotes! It started to eat tapes the minute I used it so I ordered a belt kit from Studio Sound. The kit worked, but getting to the bottom belts was a sheer pain in-the-you-know-what.
The Sanyo I found in what I'd describe as a true junk store for only ten bucks. Also found a whole bunch of Beta tapes with their labels still on their sheets, and even five of the early Magnetic Video Corp. movies, dated from 1978. The Sanyo needed belts too, but was MUCH easier to work on than the GE. Over the past couple of years I found a wired remote for it, ordered a reprint of the owners manual from Mr. Betamax, and even scored the original service manual off eBay.
I still use both from occasionally to time-shift since we don't have cable. Except I wonder my machines count in this list because I acquired them only a couple of years ago, and both were manufactured and sold quite a few years before I was even born.
