I have all Repro boards in mine...Pinscore LED display $200, new power supply from pinscore $80 (no high voltage), new interconnect board $100...new MPU (no batteries at all) $300...if you spent $250 on the game you will be in it for under $1000 and have a bulletproof Rollergames....Which you will want...since you are never getting rid of it.
Such a great game.
And sorry to 1-up you, but I got mine for free. I knew someone that had one in the living room for years kinda working. He was moving and said if you are willing to drag it out then it is yours. Gladly took it.
I also recommend LED's...
