I'm a newbie to the world of keyboards, having gone the shameful route of Logitech G15 (Died mysteriously with weird key repeating issues.) → Razer Tarantula (Entire keyboard flexes when the weight of your hand is on the keyboard.) → Microsoft Natural 4000.
I'm not entirely unhappy with the latter, but its space bar sucks, the keys are wearing down after two years of heavy use, and the plastic stands don't really lock in place so every other day I'll put too much pressure on the wrist rest and, click, in they go and I've suddenly got a declined keyboard.
In any case, having typed on a few Model Ms before I don't think I'm after buckling spring. Mechanical switches will do nicely, though I'm not exactly well versed in switch models.
I'm more interested in tactile feedback alone than tactile plus click feedback.
Lastly: I'm only interested in keyboards that have a good online distributor that ships to Canada. So far I've only found Elite Keyboards.
