@sswilson the only thing about the Corsair one, and if you have Corsair you may already have experience with this, but they have the labelling flipped on the shifted key caps. For example the number 1 is on top and the exclamation point is on the bottom. I have a Logitech that did the same thing. The argument I've read is that it is done to give the primary, non-shift key option more backlit illumination. I'm mostly a touch typer, but that still bugs me.
Small thing, yes, but just thought I would mention in case you didn't notice.
I've been very pleased with my Cooler Master MasterKeys Pro S for a TKL. Newegg.ca has it for $446.98... seems totally reasonable!
My old K90 had normal labelling too. I was basing that comment off of the pics on the BestBuy link you posted.
