I've got a million-bajillion Seiko auto's. With the exception of my Spring Drive Tuna and my SLA021 Marinemaster which I wouldn't let anything but a professional touch, anything with the cheaper auto movements are super easy to regulate on your own if you watch a couple tutorials and have tools to open the watch. Anything with the 4R36 or similar movements are cheap enough to replace the movement it isn't a catastrophe if you break it. You can get them for around 50 bucks.
However, get a demagnetizer, and in most cases it will get you regulated within the specs of the watch. It usually only takes a couple passes through the field. I am finding more and more of my watches require demagnetization as we have so many things lying around now that emit a magnetic field. The ultimate irony being, the magnetic charger for my Apple watch, I know has thrown off a few of my watches as it is on my nightstand, where I place watches at night.

However, if it's beyond that, and if you have to open the caseback, and use the regulator lever in the back of the movement, it's really hit or miss unless you have a timegrapher to see the result.

I have 50+ auto's, so it made sense to me to get one when they were a hundred bucks on a black Friday deal. But unless you have a large collection, I don't think it's worth the investment.
Edit for clarity:
When an automatic watch becomes magnetized, the balance spring ends up sticking to itself, and becomes erratic. So even regulating it with the lever on the movement, doesn't fix the erratic behaviour of the watch. So it's the point where you always want to start before you start adjusting anything else.
