I've played my little Flea to death. I own many expensive ukes that I take to my uke club meetings, but the Flea is the one that stands near the computer. It's also my 'rain ukulele' ie. the one I take for outdoor use when the weather is questionable. I have a plastic fretboard. The rosewood fretboard is needed if you plan to use any wound strings. I bought mine at Elderly Instruments on line. They usually have the lowest prices on the Flukes and Fleas.
If you are looking for uke music, look on line. There's lots of it out there. But, if you get a chord book and a ukulele fretboard rubber stamp, you can put your own chord diagrams in songs that have the chords listed. You don't have to be limited to ukulele books for tunes.
The little uke is just plain fun! It's very portable, not too difficult to play, and people usually smile when it's brought out. People don't take ukes too seriously, so there's not a lot of performance pressure. I've got enough experience so that I can usually convince an audience that it's no toy.
