bintz,
Have you already cleaned it up really good?
If not, this is a great way to fire up your appreciation for it.
Replacing worn out parts, dis-assemble/clean/re-assemble playfield parts,
clean/polish the legs & coin-door, make sure every light working, replace leg levelers, install a shiny new pinball(s), get the slope and level set as best you can for good gameplay, etc.
If the legs are in really bad shape, then you may want to replace them and the leg bolts.
Nothing wrong with keeping it, if you can't part with it, especially if it is not really in the way.
Do you feel like posting a few pics of it?
Another idea is to really try talking yourself into selling it.
Let someone else enjoy it if your not feeling it anymore.
Have a good weekend.
