Bally Strikes and Spares for $100 in working condition. What I learned:
- Learning curve is steep and progress slow, but small victories feel soooooo good!
- Start small, buy a replacement board if needed rather than try to troubleshoot and fix a board that beyond your skills (but work towards getting those skills)
- Pins can be intimidating, but it's a great hobby and pinside is full of helpful people

I'm still pretty useless when it comes to understanding how pins work and I don't think I could ever do a restoration or even playfield swap but I've learned a lot and I'm pretty comfortable I can fix most common (simple) issues
