I personally think that Kala is one of the best, most consistent brands across virtually all price points. There are folks who consistently make great mid-to-high end ukes, but almost no one makes good stuff from the real budget price points all the way up to the expensive stuff.
My first "real" uke was a Kala Ziricote concert (KA-ZCT-C), and although it is laminate, it sounds great, plays great, and is still with my collection today. Over the years, I've owned the Exotic Mahogany concert (KA-CEM) and the Pacific Walnut tenor (KA-PWT) and while I did eventually sell both of those (they were rendered redundant through bouts of UAS) they were both quite nice for their price. Well made, sounded good, played well.
My first "expensive" uke was a Kala Elite Koa 1 soprano. Although I now own instruments that cost *much* more, that is another one that I just can't bring myself to let go of. The Elite series are pretty underrated in my opinion. They are very well made, sound fantastic, and cost less than they are really worth. Particularly the latest iteration, with the wider nuts and the new X style bracing, they are truly worth checking out.
There has only been one Kala I did not like, I think it was the Solid Mahogany Soprano (KA-SMHS.) It just sounded a bit dull to me in the shop. For it's price, I wanted to like it, but it didn't speak to me.
The real hidden gem of their line, in my opinion, is the Spruce Top Flame Maple series. These have a solid spruce top with laminate spalted flame maple back and sides. They are under $300 (US) and punch way above their weight class. My wife has the tenor and plays it more than her Martin or Opio tenors. I have the concert version, and it is also great. If you get a chance, give them a try.
At the very bottom end, you have the Makala line (they are part of Kala) with the Shark and Dolphin lines. Although they are crazy colors that don't appeal to everyone, they are pretty great. I always describe them as the "cheapest ukulele I think you should play on purpose."
(My wife put a low-g Fremont Soloist on her concert Shark and it sounds shockingly good!)
A well setup Kala is a great way to play.
