This is what http://www.ukuke.co.uk/magazine.htm has to say about Mahalo ukuleles that are used by students at Cal-Mum

Much will also depend on how much money you have to spend and unlike almost every other instrument or hobby you can get away with spending very little and get a playable instrument. It is generally recognised that the Mahalo U30 coloured soprano ukes (look inside the sound hole for that number) are excellent value at around $35 and many seasoned players have one around in case they need something on the beach or for the picnic.  Most agree that they are vastly improved by re-stringing them with Aquilla Nylgut strings. Warning - There are other coloured sopranos that are no where near as good as the Mahalos.
