If your anything like me, you'll end up putting about 2 grand into it.
Seam's like every game I've returned to the living ends up costing more than I planned on.
Just getting it working isn't good enough, it's got to be right.

Bought a working Space Shuttle $600 though I can fixer up, and had the MPU die on me.
got it home and found the paint was pealing on the BG and PF needed work.
Ended up buying new BG, PF hardtop, Had to send the MPU out for repair, It was missing 1 display, so ended up getting all new RD displays.
Ended up putting 1,900 into it, so now I have a great looking SS for $2,500. What's it really worth?
Did about the same on a Xenon.
They look great but I'll never get what I put into.
But it was fun fixing them.
Good luck, I'm following.
