Looked into the k400. Great specs and love the layout. Unfortunately the lack of backlit keys is a nonstarter for me. IMO living room computing is only doable if it works in the dark (movies, nighttime gaming, etc).

That's fair. It's designed to be a budget couch keyboard.

I did concede in my edit that the op keyboard at its intended msrp of $100 is actually a pretty solid upgrade from the K400. I'd definitely consider getting it for that price but absolutely not for $400.
