Thanks for the replies, they are in line with what I had in mind. I was thinking around $4000, which is ~10% over nada used price, the dealer has it listed for over $5000. It's worth a try, at least I know that for an old bike it hasn't been hurt much.
I was thinking of riding it, as is, for a season as an "extended test ride", & taking care of the aging stuff if I kept it. I'll probably keep looking for a similar used bike that has already been upgraded for less money.
