I have a Taxi PS, D-12246, works starting with Taxi through the end of Sys11. Check your manual, or send me your game name, and I'll look up whether it will work or not.
HV section was rebuilt as one of the display voltages was missing. It has a jumper on the back as a trace was damaged. It's been fully tested and is in spec and ran rock solid in an Earthshaker I had in the shop recently.
A new Rottendog PS is $80 to $85 + shipping based on prices I see online.
$70 shipped for the board or $50 if you have a rebuildable 'core' to trade in.
