Arrrgggg... LolSeems most places are £160 for the wireless basic one.
Personally I don't think it would be of much benefit unless you are sitting doing CAD all day.
For me the Logitech MX Master mice are good, still quite expensive and I have 3, one each in workshop, home and van.



- and I was converted in minutes - I hate having to use it without one now. You don't realise how good it is until you have to go back to one mouse and buttons which I find awkward, slow and ache inducing trying to get fingers to hold mouse buttons all the time. No more lifting the mouse to get it back to the middle of the mouse pad to continue a rotate, pan etc.
