The ukes you get here are kids toys - fine for trying it, but you'll want something a lot better if you really want to play it. Look around and you can do a lot better (small and light for shipping too, so made for ordering online).
There are a whole family of ukes, tenor, soprano and all sorts. There are quite a few hybrid uke/other instuments floating around SA for some reason - Mandoleles (with double courses of strings), Banjoleles (with a skin and a pot like a banjo), etc.
BTW, check out Jake Shimabukuro for a mind-boggling uke player.
