Robm,
I reckon for $200.00 you cant go wrong. I would think parts alone in that condition would be well worth it.
I bought a Police Force (Sys 11b). Very easy to work on, there would probably be a few things you need to do but with the PinRepair guides is very very easy.
I bought a brand new PinScore display for mine (cost about $400 AUD landed) but I loved the machine so was not even an issue. My old display was 99% working before I replaced it (after repair) but still needed 1 x chip to fix. They are $20.00US and quite rare.
I'm pretty sure Greg stocks the kits to rebuild the powersupplies to. Or can be sourced from GPE if not available here.
Re the backglass. Not sure about this. I understand there are translights available for some of the Sys11b games. If there is one for you - easy solution.
The cabinet...Not sure about this one. I would work on pcb's all day long rather than fix cabs...
But I would not let it deter you.
My vote - buy it.
