Rottendog sells a replacement for $399
I have had great results with Clive at The Coim-Op Cauldron with board repairs. Had the same thing happen last fall with my Champion Pup (has the same DMD board). He repaired it quickly at a fraction of the cost of a new board. You can view his site here: http://www.coinopcauldron.com/
Some where between $4 and $4500. I would say. Also could be more depends on condition.
