Mine is currently in pieces but will be working soon after refinishing.
I recently found a MIJ AFB-100 5 string Deluxe advertised for $250 on CL. It was described as very good playable shape, just a few minor chips and scratches etc. I got there and he led me to his cold garage where it had been stored all winter - to start the neck had a 1"+ negative bow, with the 4 remaining strings stretched taut against the fretboard which had been badly defretted. It was the purple model with the gold hardware, but the hardware was rusting and the finish was just ugly.
He informed me that he put in a new battery though. I walked out with it for $90 and on the way home even regretted that much.
The truss though miraculously and instantly straightened out the neck which I thought I'd have to replace. I sanded down the fretboard some more and it looked pretty good actually. The electronics were original and surprising solid, no issues at all. A bit of Barkeepers Friend took care of all the rust. I put it together and it played and sounded just great. So smooth and easy to play, it is going to get used no matter what else I pick up.
Took it back apart to refinish, I will post pics soon but count me in...
