Hrm, that looks pretty neat, but as someone completely new to mechanical keyboards, I wonder if it would be a good starter.

Probably not, since it requires a bit more work than just a keyboard you can buy. I would say something like the CODE Keyboard, WASD Keyboard, or Ducky Shines are good and reliable keyboards.

I'm not opposed to doing some soldering - I'm mostly interested in the entry price. The lack of arrow keys concerns me a bit (but I suppose I could use their layouts to account for that). I'll give those keyboards a look though, thanks!
