I have paid $4800 for player TAFs that didn't even work. It does depend on what area of the country you are in. A really nice TAF (not HUO or HEP) can bring $7500 easily here in Colorado. I have bought and sold 12 in the past 5 years (including two Golds). PF and cabinet wear are the biggest factors that determine value IMHO. Mods that hold value are Color DMD, Sound up grades (Pinball Prosound), Invisiglass. Average players that have some pf wear, decent cabinet (some scratches and wear marks) with everything working properly and clean can fetch $5500- $5800 in this area. Above average $6000-$6500
