Been using a logitech mx1000 here for about a year now, its the best mouse ive ever had/ used, nice and smooth, sensitive so i dont have to physically move the mouse much for the cursor to move from one side of the screen to the other, its never missed a beat.
To top it off its rechargable aswell so it never needs batterys, just stick it on the dock for about 2hours every 3-6 days depending on how much you use it
