Caveat epmtor everybody.
The Kanile'a CS-DLX is a feast for the eyes. WOW! In my opinion, Kanile'as are the best looking non-custom ukuleles there are. More beautiful than almost all the customs, too.
Are they great instruments? There are differing opinions. Listen to Corey Fujimoto play one over the internet and it sounds great. But, I have played maybe a dozen or so and owned three (each very briefly). All the Kanile'as I've played have sounded dull compared to other high-level ukuleles. All of them. And, now that I listen, I hear characteristics of that in even Corey's recordings.
Some people want a low volume, muted tone. Hey, if that's you, enjoy. If you can play yours before buying, do so. If not, buy from HMS, like I did. If it doesn't meet your needs or expectations, you can exchange it. All mine had poor intonation, (one extremely poor) and were returned.
As far as the Stealth tuners are concerned, They too are pretty cool to look at. (I personally think they're too minimalist. Does the weight really make so much difference that you want something so plain looking? Definitely not to me.) But as coolkayaker1 says, There have been several legit reports of them failing and being inconsistent in their function, like one or two in a set being very tight and near impossible to adjust. The kayaker is right to point this out. That's what the forum is for, (if I may end a sentence in a preposition). Most Stealths are probably fine. I seem to remember coolkayaker1's worked well. But, let's agree to agree that the minimal, light-weight design apparently has it's down-side. They are probably not as durable or consistent as more conventional tuners.
If you're going to buy an ukulele with Stealths, you might ask if the shape of the headstock would allow you to replace them with something else if the need arose. (If it was me, I'd have the seller replace them before I bought it) The headstock problem was a very serious problem for Ryan Rodriguez when he had 2 (was it 3?) Stealths fail. But, that was a custom, with a headstock designed specifically for the Stealths.
As I said, caveat emptor.
