Tricky call really.
Personally, I wouldn't pay over $100 if it looked even close to being functional and aesthetically in good shape. They seem to sell in the $100 - $300 for EMs. At least it has "Flash", but I'd want a solid 3 go to games. Regulation, Flash/Dual Flash, and some other game you're familiar with (Strike 90 is a good one in my opinion). I know this has a few games, but do YOU like them? Also glass/plastic won't be cheap to replace, so make sure it's all there.
They're also large and heavy. That sometimes helps negotiations. As in, I'll lug this thing out of your basement for free.
A project shuffle, as in, something isn't working...
Challenges can be fun! Maybe it just needs a fuse? Or a coil is burnt? Could be an easy fix!
With that said, I wholly encourage diversity in a line up. And nobody seems intimidated by a puck bowler at parties.
Just an opinion, not gospel.
