Thinking of purchasing a child a serious but fun ukulele to start playing - you could do a lot worse than look at aNueNue (pronounced a newey newey!)
This is a relative newcomer to the ukulele market, and they make some very very nice ukuleles. I've read great things about them (their site is HERE)
But for a child, have a look at these two ukes - I think they are great - they are laminates, but very well made and have a charm all of their own
They look great fun and I know my daughter would love one!
