Here are the ones that will work in terms of using a passable sensor. I have the first one, have been using it for years. It is cheaper if you buy it from Amazon UK and ship it to the US (I'm in the US).
Some sound advice in here. This is the mouse I use for PoE and it's been spot on, I use the two side buttons for flasks 1 and 2 and the left, up and right on the joystick/rocker for flasks 3, 4 and 5.

I got myself a nice, ergonomic office chair from Argos too but I can't find a link for that right now, it really helped though.
