As has been said above, it is relatively easy to learn, I'd say as easy as a guitar, banjo, concertina. It would depend on what level you want to get to. I bought a UBASS - a great instrument.

Uke Orchestra of GB - brilliant. Go see them if you can.

As for GUEST above - Regarding the ukulele phenomenon I've noticed it too. Especially in for young/teen girls or effeminate guys.

LOL What a stupid remark. Yes I did LOL.
