Peripherals Mouse advice

My father in law (early 60's) want an new mouse for Christmas.

He doesn't game, always sits at a desk in his study (making wireless of limited value) and mainly browses the internet or uses office packages. Based on that, I'm looking for a wired mouse with a limited number of buttons.

No budget constraints if there is a value, but anyone got any suggestions?

I'm thinking a Logitech M500 for about £25 (as I like my G600 gaming mouse from them) but open to any suggestions.

 

I'd focus on ergonomics. Do they have any complaints about their current mouse (too small or too large for their preferred grip)? Any wrist or elbow issues that might make a vertical mouse worthwhile?

 

He is is pretty good nick physically, but I will double check. That's a good shout thanks!

 

I like the G403, after going through 2-3 MX518 and wanting something with a higher DPI.

 

I like my G403 too, but mice are such a subjective thing...
