Anyone recommend a good ergonomic keyboard and mouse that's bluetooth? Mr A and my wireless keyboards and mice keep clashing and it's getting frustrating, plus my 'P' key sometimes takes several presses before the P comes out, not good when you code in php

I've looked briefly on Amazon, and on the MS site (as I like the MS keyboards and currently have one) but their ergo ones don't have number pads! Most of the ergo keyboards I can see on amazon have a naff mouse too.

Update: Bought a logitech MX5000 one. Bluetooth yes, decent mouse but standard keyboard. Unfortunately the bluetooth ergo keyboard had a naff mouse, and I can manage with a standard keyboard but need a better mouse.
