Wireless Mouse For Laptop Less Than 1000.

Hi All,
I need a good wireless mouse to use with my laptop. This is only for casual browsing and office work. Not for gaming. I would like suggestions from good brands like Logitech / HP /Dell / Lenovo /Microsoft.
Also i am using a logitech M100r wired and would like something which closer to its dimensions. Meaning conventional size and design and not too small one.
