I loved the old Model M I somehow got as an impressionable youth, back when PS/2 keyboards were fancy and USB keyboards weren't a thing yet.
Eventually I moved away to USB keyboards and hated the mush feel and looked around for options but balked at the price. Finally I ran into a couple of guys who'd made the jump (not to Das though) and I started looking around. I found the DKs to be really good looking and I really like how they feel (I've got the clickiest switches they offer for the Mac).
I think over $200 for a keyboard is crazy as well, especially if it's because people are getting conned into thinking they're getting more than they really are, but I won't begrudge someone's decision if it came down to, "I know what I'm getting and I'm fine paying this premium because of [insert deciding factor]"
I wouldn't do it, but 10 years ago I wouldn't have spent $120-150 on a keyboard either.
