I am quite interested in that Excalibur v2 keyboard!
Back in the days I was evaluating peripherals for the impact they might have on my experience as a user, I concluded that a mechanical keyboard was not quite worth the expense but, if I were to get one, I would favor a full-size keyboard with Cherry MX Brown switches. I do not like noisy keyboards, but feedback on key activation is important!
Now, as an Auditor, I spend all day on a ten-key with mechanical switches; and it really does make a difference! Not needing to mash the key for activation, and having that tactile feedback to whether the key has been activated, is a wonder for my accuracy when I'm going fast. By touch alone, never looking at what I've entered, I know if I've made a mistake.
