Mechanical Keyboards

I've been using my first ever mechanical keyboard (Cougar Vantar MX) for like 3 years but recently a few keys broke and it doesn't have hot swap so yea I need a new one. The budget is up to $100 but closer to 50 would be preferred.

Requirements:

• Has to be mechanical lol.

• Has to be 100% with numpad due to simulation software I use. Without a numpad the software is truly hard to use.

• Has to be wired as I do play multiplayer games. Dual connectivity is fine only if latency is not impacted at all.

• Has to be black because my whole setup is black. Grey accents could be fine though.

• Has to be normal size. Now this one is important. My desk is tiny and the mouse is under the keyboard so every millimeter of vertical space matters. Obviously arm rest is a no go. No super low profile either though. I do need key travel.

• Has to have linear switches. I'm not picky about that but just don't make it 200g or 0.5mm of sensor distance. Something Cherry MX Red esque would be perfect.

Preferences:

• Separate volume control and mute keys/lever. I'm no fan of FN+F3.

• Proper RGB with on board memory.

• Decent reliability lol.

Not important:

• PBN/ABS keycaps.

• macros and other advanced features.

• basically anything very advanced.
