Squier has the Vinatge Modified Jazz Fretless for about $300 new Sunburst only, I think) hear good things about it. They also have a VM Jazz 5 string (natural finish, blocked and bound maple board) that you may want to check out. If it's anything like it's 4 string twin (which I have and love) then it could be a good one as well. As far as I know Squier makes no 5+ string fretlesses.
