I'm about to purchase my first mechanical keyboard.
I've been using a Microsoft Natural Ergonomic 4000 for the past seven years, so the keycaps are all shiny and have that oily feeling. Here's how it would have looked new:

What really bothers me about that keyboard is the spacebar which is very hard to press and squeaky, and overall the keys require non-uniform amounts of force to press down. Also, most keys, especially escape/tidle and the function keys, wiggle around a lot. I feel like the right side of the keyboard is not very ergonomic, maybe the way it's angled and the oversized keys cause me to twist my right hand much more than on the left side. Oh and of course the thing is way too large, so I need a TKL.
Wondering which of those two I should get:
Ducky One TKL PBT
Leopold FC750R
I'm also open to entirely different suggestions!
