Well you must be one of the lucky few with much monies, if you've got enough for a £240 keyboard I'm sure you also have a 9900k paired with a 2080ti and a nice ultrawide 120hz monitor. You are right their is a market for it, but that market will be tiny.£240 for what? I simply don't understand.
I'd pay £240 for a keyboard with exemplary build quality and an absurd no quibble warranty. I reckon there could even be a market for something like that. It's not like people replace their keyboard very often.
