I had a tenor uke which was very nice, but which was rarely played when I commissioned my tenor guitar. I now have a fairly expensive soprano, by Kala I think, made from Koa wood and with a Fishman pickup in it. Probably in the region of $150 US.

Tip 1: Always buy the best you can afford - usually easier to play and will sell for a better price than a cheap one should you want to quit playing it.

Tip 2: Always check the intonation up the fretboard and on the octave. These little instruments can often go out of tune the further up the neck you go - very noticeable on a very short-scale instrument.

Come over to my place when you've got one and we'll play some duets. It's around 5,000 miles of course, but there you go...
