WTF I thought this was a Black Hole thread, not Jumping Jack!
Anyway, both these games are my all-time favorite EM and SS games. I did similar repaint job on my Jumping Jack - looking at your pice brought back some not so great memories lol.
I just did a Black Hole playfield swap for some new Mirco playfields. Took about 40 hours in total for both. All the mechs were clean (I had previously shopped the playfield several years ago) so I didn't have to worry about dealing with that which speeded up the process. It was well worth effort.
