Thanks fellas,
Wasn't trying to put anyone on the spot, just that this came out of left field and wanted an idea.
Thinking I need a Stern again, been a long time.
I'm with you Daniel, if the playfield and BG are in reasonable nick then I like to get the rest of the machine going.
Cleaning and Krylon is as far as I go with a BG, and if there is heavy wear on the playfield I tend to offer bugger all or let it slide.
If I get somewhere I will let you all know.
