Ask HN: how do i find a new keyboard just like my old keyboard

Whenever i use any keyboard other than my benq a800 (which is not being made anymore) I start to get wrist pain after a couple of days.

I would really like to remove my dependency from the benq and get a new wireless keyboard but I've bought 3 or 4 keyboards and have to keep on going back to the benq.

Anyone have any suggestions about how i can find a new keyboard with the same button action as the benq?
