My first affordable fretless bass was a Slammer Blitz Bass BZ4 in cobalt blue. I had a lot of fun with it, and i would recommend it to the curious bass player for a cheap exploration into the fretless world.
I had a fretless Cort Curbow with Ebonol fingerboard, not a pleasant memory... Go with wood all the way! And whatever you do, save yourself time, money and hassle, and do not do business with buzzardsbass!
