Dirt != Scratch. Yes scratches are bad, but they have to be fairly deep to
trip up a good player. As long as they're on the front side they can be
polished out as well.

There were some with degradeable dye that came out for a short while, it was
a ridiculous idea and was quickly scrapped. Even the writeable DVD's are
supposed to last 10-20+ years, pressed discs should last much longer unless
they're defective and delaminate.

Pretty rare though, I've seen this exactly once, failed capacitor in the PSU
of a cheap Apex player caused it to eject while the disc was spinning. I
can't count the number of tapes I've had destroyed by a VCR when the takeup
spool didn't wind, threading mechanism jammed, etc.

Switching to the metric system (would have been nice) would require a huge
overhaul of the entire infrastructure, factories with machine tools,
textbooks, measuring devices, road signs, gas pumps, etc. The switch to DVD
is almost complete, new movies all come out on DVD first, VHS is an
afterthought and goes to the bargain bin. Something new will come along
eventually but I suspect there will be backward compatibility as it's not
hard to implement. Our existing DVD collections will play on modern players
many years ahead.

If the laser burns out, throw away the player and pick up a new one with the
latest features for $50-$75. They last as long as VCR's, unless you buy a
$1500 professional deck or are lucky enough to have a high end Sony or
Panasonic from the early 90's. It'd be nice if "people stick with what
works" but in america that seems not to be the case, people hop on the
latest and greatest bandwagon. I tend to stick with what works when I can,
but in this case something else came along that was clearly superior. I
could still ride a horse to work if I wanted, but it's hard to argue that it
would work better than taking a car.

Bet what you want, but it's pretty clear VHS is the one that's fading. DVD
is outselling VCR's 10 to 1. I wish you luck making a living repairing them
but urge you to proceed cautiously. I haven't had someone bring me a VCR to
fix in at least 5 years and when I have picked up even reasonably nice Hi-Fi
units I can only get $15-$25 for them in good working condition. 5 years ago
I was getting $100 for them, and I could get $25 for even a low end cheapy,
today I can't even give away something that's not 4 head hi-fi, ended up
thowing away an old Funai and gave a Panasonic 2 head fully working with a
remote to the local thrift store after trying unsuccessfully to give them
away for free for several weeks. If you like the technology that's great,
keep and maintain some nice units for yourself, I have a couple of high-end
Sony's I fixed up, but in the end I don't remember the last time I've used
them.
