you can consider a fretted bass lah, main problem with people going from fretted to fretless is getting good intonation. not much other difference in terms of playing. even if you used a fretless instead of a fretted you would still have to get used to the scale length and playing style of an electric bass. the learning curve is more or less the same. and eventually you would want a fretted bass if u start playing other kinds of music, because of the difference in tone.
take the lefties for instance, many of them just end up playing a right handed bass and get used to it
