These Hadean brand bass ukes usually get decent reviews if you just want
to spend a little $$ for a trial run...I have one of the solid body electrics (I know , a different beasty) in white and like it a lot. It has the rubbery type strings but I have found a bowlers powder pack up and down them a couple of times before playing helps a lot, just wipe the strings and fret board after playing..
