I Getcha...my Bn30 is by far my best. the newer, bolt-on neck models are pretty good though. There was a Bn-20 on Seattle craigslist that shows up every once in a while. I don't think it sold. he just gave up...could return.
If a baritone ukulele sound is your goal, the early, dovetail nui's are superior. If a tenor guitar sound id what you're looking for, both the new and the older versions sound alike with Thomastik-Infeld wound nylon .016 and .024 E and B strings.
