Hi karlb. Welcome to Geekhack.
I love Corsair's K65s and K70s, gaming brand or not.
Personally, I have only been drawn to the Heavy
Metal Keyboards GB myself. Plenty of size and layout options. Steel cases. No hot swap though.
You get a lot more options moving down to the 60%-65% size, unfortunately. KPrepublic had a stainless TKL kit, and a stainless case available for it, but that looks to have been taken down.
I don't look into/watch much of that stuff either though.
What switches have you tried? Which do you like?
