I would get an estimate for the repair cost before committing to getting it fixed.
I managed to get all of mine (inexpensively) - and I was just thinking about how much I would be willing to spend to get one of them "fixed" if that was the only machine I had available to me.
When one can buy "new" for around $100 or so - it becomes sort of a hard decision to make on whether to spend the money on an old machine (that will probably run "forever" if one can get parts for it) or a new one that might have a one year warranty on it.
The 237 weighs quite a bit - so it was "portable" when I was younger and stronger.
