What's being discussed is not "holy grail", but rather your personal notion of an ideal instrument. I've owned some sought after ukuleles in the past. I once had a Kamaka KOA tenor, and also a pristine 1950 Martin soprano. Neither stood out for me, among all the now 39 total ukuleles that I've owned. I'm currently back to 21, up from 19 in the last month. The ones I truly enjoy happen to have cost me comparatively little. Their value to you is not a criteria for me. I'm able to coax sweet tones from the ukuleles I own.
I'm an easily pleased guy. Pb&J sandwiches are still a favorite. My wife still makes me (very) happy. I really like my now 7 year old car, although I'm not a car guy either. I'm just content.
