There are a lot of very good mid priced ukes available and there is probably not much to choose between them in quality. One thing to watch for is that they are properly set up. Many otherwise good quality ukes come with indifferent setup and it can make all the difference to playability.

A decent retailer should set them up before selling them but if they don't either find someone to do it for you or many folks do it themselves. There is plenty of advice online on uke setup.
