Counting out paying for exclusiveness or limited-edition stuff, it's really pretty hard to go over, say $600 with a keyboard. You can get your LED side lights, backlighting, an anodized aluminum case and choice of switches for, what, $350? And even the most expensive keycap sets (not made of gold or something) rarely push $150. Not sure how much a full Raindrop V1 set is (which afaik is pretty expensive), but even then I doubt people would pay more than $100 at most.
