I can certainly vouch for the more recent JVC decks. Very simple mechanically, and at least around here parts like clutches and belts are still easily available. Some JVC chassis though are to be avoided.
I have a recent Mitsubishi, works really well, has since new, but no parts for when it does give trouble:tears:
Wouldn't touch anything Panasonic unless it had a D deck or older mechanism. (But not too many HiFi models) More recent ones have power supply issues in a big way and have a knack for all things wearing out at the same time, good design in some ways, but a nightmare on the second hand market. On the up side, parts for all but the most recent ones are still available, but at a ridiculous price.
Sony VHS is generally not to be bothered with in my experience, costly parts and early motor failure can be an issue. The best of the older ones can be a mechanical nightmare. The most recent ones here used a Samsung deck with a small gear in part of the clutch that broke in two. Regular cause of failure on these.
Of some of the old ones, i have had great experience with older Akais, some are pretty nice, built like tanks and not too hard to work on. Hard to find in HiFi though.
In this country working Beta machines go for stratospheric prices, especially if they are HiFi units. Sony units are popular, but the Sanyo decks are generally more sought after as they are generally considered more durable. Other brands can be hard to source parts for. But all these old decks can have problems that could write them off. Have to be careful and well research your purchase.
