So far I've been able to remove the boards and send in for repair as needed. But if I ever get stuck on something, not any good options for me to be able to move and take it in for repair. It's too wide and heavy. If you have that option then you should be good. Lots of help here but depends how much you want to keep racking your brain on troubleshooting. It's not an easy game to figure out stuff.

They can be a pain to repair for sure. The subway system has so many opto's and a few known problem areas like the trough boards. Once you get the pin dialed in there great. I think you will be fine.

It can be work, for sure, but I think it is worth it. I have had few problems since getting past the initial issues. The likeliest repair (at least from my experience) will be replacing the wiring harness to one or both cannons. It's not that hard, honestly.

I have rebuilt 3 and I am working on my 4th. Once you go trough it all the way 100% I believe you will have as little or less than normal issues with the pin. When you remove everything from under the PF ....take your time. I would recommend saving some repair time and remove the subway clean all of the inserts and change over to LED bottom side. When subway is off replace the subway coils and re flow all of the optos on the vuks and subway itself. Also replace the ball trough boards ....if they are not bad they will be at some point.

Install the subway reinforcements from Marco - replace the stock weldement for start scoop with replacement from Marco. Again just a few tips.

Also, replace the fkn crappy IDC connectors to the trough board. If these are flaky you will get all manner of weird and wonderful errors such as 2 balls being delivered to the shooter. All the optos must be working solidly for this game not to be royally screwed up!!! Fantastic game though
