There is 60th Anniversary MIM Fretless Jazz that I have laid away as either a Christmas or a birthday present to myself. I love fretless, but I have never kept one for long. This one may break the streak because it is a great combination of being inexpensive and well made. That said, I keep thinking that I would get more out of another five since the only place I play is church, and I use the B string a lot.
So, I stick with fretted fives, knowing that I don't have the interest in putting in the necessary time to get my fretless skillz gig-ready.
