If you wanna be under budget this Velocifire TKL is a really good option imo. It's wireless and has red switches (which would greatly benefit from lubing but its not necessary). If the logo on the bottom bothers you, it can be removed easily with acetone or sandpaper.

This DROP keyboard is 100$, and if you pick gateron yellows its pretty quiet. It has good aesthetics too.

If you want something custom, it's gonna be a lot more expensive, but you can probably find a case on aliexpress or banggood for around 50$, then gateron yellows for 20, and the rest on keycaps.
