My first game was a basket case Fish Tales!
My advice?
As said above, clean it up,
replace the playfield insert decals,
Replace rubbers
Try to live with the translite an cab decals
Replace the flipper coil(s) sleeve(s) spring(s)
Have a look at the boards, have any been replaced by aftermarket? If so that's great
If not, is there alot of corrosion?
Ultimately my game was probably worse than yours but when I bought mine it's was 650.00
Do the things that make it play well, asthetics will only eat your time and wallet, a players game is fine
