If you're a beginner and don't have much experience with instruments - it is best to buy from a reputable seller that does setups, eg: The Ukulele Site, MIMs ukulele store, Uke Republic.
The ukuleles sometimes aren't in great playing condition even if brand new if not setup. I have enough experience tinkering with instruments to do my own setups, but even then I would rather buy from a seller that does it for me. It's simply better value and I have the peace of mind buying from a seller who understands ukuleles.
The Kala KCGE-C is probably an OK instrument.
If I had your money, I would probably go for a Pono from The Ukulele Site too.
You can pay a little extra to have a professional pickup installed.
