I've tried a lot of really nice mech keyboards but this is the one thing that makes me go back to my 'ThinkPad TrackPoint Keyboard II'. It's super nice to never have to leave home row and I definitely feel the relief in terms of RSI.
Considering the embarassing amount of money I spent on other mechanical keyboards this is definitely in the affordable category.
What switches are you using? I am always afraid of the noise level with mech switches but I have used silent reds and they were ok for me noise wise.
Again, stupidly expensive keyboard for what it is. However, I can totally see myself picking up another one as backup in a few years. It really is a layout that feels right.
