Gameplay on this title is average anyway. It's getting more love these days as people spend more time looking at older games with the lack of new ones, but it is a very average machine.
Have to disagree with this (although i know pinball is a very personal preference thing), as its one game that i absolutely love - the sound is great, and while the gameplay is not overly deep, i find it much much more enjoyable than other 'shallow' games such as Getaway and Fishtales.
I'm a bit like you carnut, in that i love doing the restoration stuff, but i tend to agree with others that this is probably up over what i would be prepared to pay for it.
DMD $220
Canon (if you can get it) + decals $150 - $300 (no idea - maybe more?)
Board repairs - maybe just time if you can do them, otherwise up to $200 - $300
All the SINK SHIP letters have pretty obvious outlining around the inserts, plus the wear in the main part of the playfield that you look at - this is not really a touch up, but a full on job to rebuild the area - plus it is prone to more wear if the cannon is not adjusted properly (people say this is hard but i've had two Black Roses, both were easy enough to adjust)
Plastics if you wanted a new set
Cab touch ups
If you are keen, go for it as it will be an extremely rewarding process.
But i reckon you are better off looking for the same title in better condition (if the pf and cannon were good on this particular machine i would prob go up to $1300)
Good luck
