Just to play Devil's Advocate, I say keep searching... just don't expect any bargains on eBay!
Two of my three pins were sub-£200 "project" pins, both early Bally solid-state games, PARAGON (£150) and GOLD BALL (£125). I've had to do lots of repairs, including electronics fault finding on the motherboard, rebuilding the power supplies, etc., but most certainly haven't spent £100s of pounds. Mostly it's a case of taking everything apart, giving it a good clean, polishing metal bits, the odd small repair, replace worn out bits, like coil sleeves and put it back together. I've made my own spare parts where none were available (cover plate on GOLD BALL) or were too expensive to justify (Nylon "buttons" for Bally linear flippers). Have a flick through my shop logs (linked in my signature below this message) to see the sort of effort I've put in. PARAGON is still a project, but the total playfield restoration on GOLD BALL is finished and it's a corker, if I do say so myself!
My third pin is another Bally solid-state, VECTOR. This was bought as a working game for £350. Eventually it too will receive an overhaul, but for now it's still great fun to play and tinker with.
Personally, I'd be a little cautious of
starting out with an E/M (electro-mechanical) unless you're an absolute whizz with Mecanno or model engineering! Parts are definitely not as easy to find as those from the "classic era" of early solid-state games like my Bally's. There's not as much info on the web or documentation, manuals or service guides. There are way more people who know about solid-state or modern-era pins than know about E/Ms. I'm not saying never or trying to put you off, just be careful diving in at the obscure deep end. That said, PARAGON was my first pin and I knew nothing about pinball machines and I've loved every minute learning. I'd love an E/M and will eventually pick up a project to fiddle with... one day
