Best Mechanical Keyboard Under $100?

Mechanical keyboards are a very personal option. There are many things that goes into a mechanical board that varies from person to person, thus one keyboard is not "better" than another (except in terms of quality of course).
You need to answer some questions before we are able to determine which keyboard might fit you the best:
1. Which key switch do you prefer? The most popular switches are Cherry MX Blues, Reds, Browns, and Blacks. The other switches (Cherry MX Greens, Clears, Grays, and Topre) are more rare and expensive.

2. Do you want macro keys?

3. Do you want LED backlighting? If so, what color would you prefer the most? The second most?

4. Do you want a full size keyboard with the number pad, or do you prefer a smaller size keyboard without the number pad? Or maybe a compact layout like the CM Quickfire TK where they integrated the arrow keys into the number pad?
