Buyers are now realising what restorers have known for quite some time from first hand experience - replacement parts are a sizeable chunk of the restoration cost.
Almost $500 to replace all the ramps on a CFTBL.
$160 for a plastic set.
Hologram repro is $400.
$1000+ in primary parts to get it up to acceptable standard for a decent pinball machine restoration. Playfield resto/clearcoat and cabinet decal replacement is on top of that for a high end restore.
Seller has the right idea since he would be paying someone else to do all that work - you could pump all those $$$ into a B plus title like CFTBL and break even, or you flog it off as a project (and he has already got his money back based on the current price.)
EDIT: Just reread the listing, new DMD required add another $300.
