I'm really thankful to all of you.
Big thanks to you - tex_live_utility, for confirming me, NPKC seems to be the right budget option, as i said before.
You can still buy a set made by BSP.

I'm confused - paying 160$ for a TKL PBT set, even though it's BSP made, appears to be kind of questionable, so to speak.
I would love to read an opinion from long-term holder.
A lot of spheres in keyboards community, are nothing but pumping ballons and hopping on hype-trains, that's why im so demanding.
"Price-quality" value, is a principle.
Well, as much as I can see, the quality of GMK keycaps changed nothing compared to the OG Cherry doubleshots.
Here's an image of my 1996 made Cherry G80-9009HAU
They're 23 years old, they look exactly the same as brand new GMK sets. They're expensive, because it's hard to produce them, and their lettering will never degrade at all. My set was scracthed up a little bit, but after washing them, and very gently scraping the keycaps with a sponge, (using the gritty green surface) they still look absolutely fantastic, expect the slight yellowing, and the slight degradation of the color red keycaps. Red dye seems pretty UV unstable.
I see where your money goes, if you buy a set like this, but they're extremely overpriced due to the doubleshot hype. I wouldn't buy a set like this due to the high prices... I got this keyboard for 50$, which was a very nice deal for just the keycaps itself, but I got a nice and rare keyboard with it for that price too. I'm used this keyboard as my daily driver for 3 months, but sadly for the summer, I had to move to a different dorm, where it would occupy all the space on my desk...
