I think Kala have got a lot of things right with their acacia range of ukes. They're obviously going after a more serious ukulele player but they're keeping it affordable by using Acacia wood (a close relation of koa and much cheaper) and manufacturing it in China.
Definitely worth checking these out if you're in the market for a quality uke but don't have a massive budget.
