okay, final decision time,

red switch, is RM203.22
blue switch, is RM187.10

which to go for?

i use a brown switch, there are couple points that can highlight mech keyboards:

1. you can make cosmetics for the keyboard by changing keycaps
2. less fatigue typing on mechs
3. much more durable than your everyday keyboard
4. sturdier build and is heavier

The jump from Rubber dome to Mx Switches is a big jump, and feels nice.
Jumping from MX to Topre, you might not feel the difference at all, at first. The difference is in the more solid, smoother keypresses. Feels like how a proper rubber dome should be made.

As Kai said, the different are not as obvious as you switch from membrane to Cherry Mx,
but as time goes by, the Topre switch will grow in to you slowly,
until you one day when you try Cherry again, you will feel that the Cherry are not so good.

When I use Cherry Mx switches, I feel that they are content and good,
but when I change to Topres, I feel that there are some different that are difficult to describe,
after using it for a few months, I pull out my Cherry Mx red again to type on,
I feel that the Cherry are not so comfortable to type on compare to Topre.

The Topre switches is very unique, even if you tried it, you might not get a hold of how it feel,
people need time to get used to it, and once you are used to it, you will never want to use any other switches.

If you have the money, it's the next step to go after trying out MX.
