A buddy of mine has a B3 for sale. Been in a private home all its life...never on a gig. Mint condition and includes the whole nine yards, including warranty, which he say is now being honored by Suzuki.
If anyone is interest, I can give put you in touch with him direct.
BTW... I don't know why he got it in the first place. He is not a player. I suspect he got a good deal on it and thought he would like to learn to play it...but....well...that is a monster of an instrument for a novice to learn.
