Thanks for another great review Baz!
I admit that when a total uke newbie, I was drawn in by both the looks and marketing of Luna. (never bought one though)
This was prior to discovering UU. Back in April 2013, I was told to look at Kala instead. I'm glad I did. I was VERY happy with the Kala KA-T that I purchased in a local mom & pop music shop for ~$129. Almost same price as Amazon, BUT and it's a BIG BUT (bug butt - ha ha) I got to PLAY it first, as well as the KA-S, KA-C and KA-B models, which was let me decide that a tenor was the better fit coming from guitar.
Surprising to me that in many shops near me that carry Gretsch, Stagg, Alvarez, Luna and Mitchell ukes, the LUNA tattoo concert and tenor ukes all SOUNDED much better to me than the others. However, similar to your review, the Luna would have always needed work on the rough fret edges and to correct the intonation.
It also seems to me that there are more female players of Luna ukes (if YouTube is a fair representation), since the parent company seems to market the Luna brand for girls and the 'Dean' brand for boys (for the teenage market).
However, like with the Epiphone LP uke, you are likely to get waves of argument as to the merits of Luna from their die-hard fans. There's nothing wrong with that, but a spade is a spade, no matter the amount of glitter on it's surface.
So yes, for ~$100, there are MANY better options, but sadly many newbies dont understand when they are looking at reviews that a fancy design makes no sound and they pay for that design instead of a well-built and good sounding/playing instrument 'out of the box'.
