Judging by the flood of responses to this topic I'm sure everyone is on tenterhooks wondering which keyboard I finally went with so I thought I'd give an update
I was leaning towards the IBM style one, but decided to go into my local EB Games here in Oz to test out lots of different brands. The poor bloke spent about an hour unboxing and re-boxing keyboards for me, and I wound up walking out with the Razer Huntsman. Pricey, but the minute I touched it I knew I'd found 'the one'.
The other keyboards I tried just didn't compare. The Hunstman is so damn 'clicky' and the response is instant, I barely have to touch the keys. That was something that used to bug me with other keyboards, I was having to use more pressure and was constantly going back over my words to fill in missing letters. With the Razer my fingers just fly over the keys. The clicks are loud and might bug some (one of my kids has already mentioned he can hear me from the lounge room) but personally I love the sound, it adds to the experience for me. I thought the lighting would be a distraction, but it's not, it's just pretty. I bought a new mouse to go with it, and now my build is pretty much complete. It's such a pleasure to use, I've already written more this week than I have in the past month. I could have bought a different brand mechanical keyboard online for cheaper I suppose, but I'm a tactile person and very picky. I don't have time to mess around with sending things back if it's not quite right, so I feel good about my choice.
I'm a happy camper
