At least in So Cal, there seems to be lessening interest in CF compared to years ago. Auction prices for readily available EM titles seem to be dropping (unless they are in exceptional condition). What used to easily be a $1500-$2000 pin, seems to be closer to $800-$1000 these days. Obviously, condition is King so prices go up or down accordingly.
If it is truly an 8 all around, I would think an offer around $500 would be fair since it sounds like it needs a number of hours of TLC. Captains tend to have an area in the blue above the Drop Targets that goes bad as well as losing paint around the bonus inserts. If this example has a better than average playfield, then it still might be a $600-$800 pin.
