I picked up another white Alps board, this time it's a Dan-branded board. It feels exactly the same as the Ortek, but it is very "pingy", whereas the Ortek has a more plasticy clack. I think that I'm moving towards the Blue-stem Cherry MX again because I prefer the lightness and whilst they're loud, they're not "too damn loud".
Having said all that, I believe that the holy grail of keyboards is with buckling springs. There's just something about them.
