I would consider these: https://www.modelfkeyboards.com/ instead, if you’re the kind of person who really uses something for 25 years at a time. You won’t care about the cost amortized over that period, and the build quality is really much higher. Unicomp is not bad, but Model F Labs is simply higher.
Alternatively, look at whatever other keyboard you want to try in a modern layout (Keebio has some amazing kits) and get a super tactile switch, like a Kailh Box Jade or Box Navy. It’s true that Cherry MX aren’t always amazing, but also, the keyswitch world is a rich place if you want to experiment, and many switch types are every bit as accurate as buckling spring. Naturally, they’ll have a different feel, the buckling spring is really an outlier, but a good switch doesn’t double or anything really off by default.
Keebio has a bunch of options on their keyboards for arbitrarily bindable rotary encoders… this is super handy for media control. https://keeb.io
