Ike is spot on about tuners; these can be dire on entry level instruments.So look out for the description of the pegs; you are likely to get better quality at the upper end of your budget, if you don't have the skills to change tuners on an instrument.

A further point to share; I have a cheap laminate soprano uke and it also needed to have attention to the nut and bridge because the action was so high that the intonation was out. I am fortunate to have an OH who is an amatuer luthier so he made the necessary adjustments. With a set of Aquila strings on it this cheap uke is my favourite work desk toy (though the people who share my office could have a thing or two to say about that!)
