The quality to price ratio can be so variable that I recommend trying the instrument first, if you can. The main problem with ukes is that the intonation can be really crap, even on non-cheap instruments. I've got a Kala KA-KCGE-C Electro Acoustic Concert Ukulele, which was about £220 at the time I bought it, and that just about cuts it.

My grandson has one that cost about £75, and that's almost as good, but without the pickup. I had a cheapo one once, and it sounded terrible beyond the 3rd fret! But... the margin between acceptable and unacceptable is really fine - so try it.
