Yeah, I pondered getting a unicomp for a long time, but sadly after shipping to EU and VAT, it doubles in price. Vintage model Ms are missing meta and menu keys which I use constantly. Most of the ANSI models are located in the USA as well so same issue as unicomps.
I don't need it to be as heavy as a model M, but similar dimension wise, I find it pleasing to the eye and the pencil tray (or something with a similar function) will help with not having pen(cil)s roll around my table.
I know of the keychrons already but both 100% keyboards they have are 108 key which I find ugly to look at and I don't have a use for the extra keys to be honest.
I've actually seen a bunch of "left handed" full size keyboards that would otherwise fit what I'm looking for but the issue lies in the "left handed"-ness of them. Yes, I'm left handed my self but I frankly don't feel like unlearning many years worth of muscle memory just to learn how to use the numpad on the wrong side.
I've actually pretty much given up on searching, haha. Every few months I just do a few quick searches through forums / reddit to see if something has showed up but nothing so far.
