Came here after watching this video.
Let's talk about this video a little.
First though, a disclaimer (that may actually have some relevance): I am only responding to this so I can type on my Unicomp (manufactured in late April of this year). So take this opinion as you will, although I freaking love typing on this keyboard. This keyboard is, for me, what the cool nerds call the "daily driver." (Is that, like, a car reference? I'm not cool, so I don't know.)
Anyway, the issue with the video being referenced is that the keyboard that he's reviewing was built in 2009 and seems to be from a period in Unicomp's history when the build quality of those boards apparently suffered some. Then again, he's comparing his board that was retailing at the time for, I believe, about $85, to the Model M keyboards that IBM was building in the 80s that was going for something in the inflation-adjusted neighborhood of about $350 or so.
I could go on and on, but suffice to say that many of the Youtube videos reviewing Unicomp keyboards seem to be authored by folks who are deeply enthusiastic for, and seem to have a fierce loyalty to, the old Model M keyboards.
Now, nothing against those old keyboards, but the fact is they have an inherent design flaw that feels pretty much like a stacked game of Russian roulette. Honestly, I'm not the person to talk about that; it's covered much better here (at around 9:45):
It seems to me like it's a you-pays-your-money-and-you-takes-your-chances kind of thing if you go shopping for one of those vintage boards.
That was my rationale. And amidst all this rambling I tend to do, let me be clear about one thing:
Unicomp keyboards are great. They really are. I use mine every morning and then pull out my Matias most, but not all, afternoons.
Incidentally, Unicomp seems to be experimenting with the prices of their keyboards recently. Either they know what they have and demand is going up or they're suffering from the pandemic the way many businesses are and are trying to compensate.
