hi, and excuse me for bumping this topic
i am used to the same key layout as the OP but prefere low-profile keys
so here's some things i've found with the same layout
first of all, my 3 keyboards at the moment:
the silver one is low-profile (slim) and is very nice
the one in the middle is Sigma and pretty much sucks
the Unitek is okay
now, long ago, i bought a cheap slim keyboard which turned out to be the best keyboards i've had.. i typed very fast and with almost no typos
the keyboard was "SuperPower" and had a silly logo, well it's long gone now
i started looking for it but couldn't find anything till i saw that logo, then with lots of bouncing around the corners of the internet - i found the full name and model
Codegen SuperPower KM-1001
iirc mine had cyrillic letters as well, but otherwise identical
it took me some time to realize that the keyboard i've had under my nose (the slim one from the first pic, which i'm typing on right now) is actually almost the same
i never considered that since the keys, and specifically the letters.. the horizontal offset is 50% which is rather uncommon:
and has the 3 annoying buttons above the arrows which i remove because accidents ;]
today i found this:
which has the same characteristic of the 50% offset as my current keyboard, but lacks the 3 annoying buttons
and i found this same keyboard but with the 3 buttons in a black variant:
and shown (on the website) as Prestigio KM 1001
