I've used the hanalima pre-cut fret boards. They're very good
BUT...check your scale length. Measure from the nut to the 12th fret and double it. If its different than the pre-cut scale lenth, it won't play in tune unless you move the bridge too. :wallbash:
However... As far as I know, they have precut fingerboards, but not exactly "ready-made," because you still have to install the fret wires... so be aware of that.
