One and a half.
Of course, the one is my favourite. It's a soprano by Pablo Kiernan, an Argentinian luthier. It is very well built, and sound very good, although not so good with the current strings I have on it (classic guitar strings... I can get ukulele strings now, who would guess I'd have to move to a country with a tenth of the population to find a music store that carried them, and about five different types). The only thing about it is that as I'm learning more, I'm noticing the intonation is not as perfect on the higher frets, but that might be my technique (if I fret too hard the note can be a bit sharp, am I right).
The half one is a very very cheap chinese ukulele I bought at a music shop just to have something to strum on while I waited the three months it took Pablo Kiernan to build the one. It was completely unplayable out of the box. I may now take some tools to it and turn it into at least a beater for when small kids or big drunks are around.
I'm thinking of expanding the family quite drastically, though. I'd like to have a concert and a tenor, so I'm evaluating a couple of different makers to buy from. And I may do some long trip through Latinamerica next year, so I'm quite tempted to get one of those plastic ukes that are on kickstarter now to just tie it to my backpack and not worry about getting it wet, dirty or anything.
