I have a Microsoft Sidewinder Mouse, it was rather pricey but I bought it for several reasons: one, my old MS Intellimouse Explorer was equally pricey but served me fine for years (that's not to say that cheaper mice can't do the same), two, I like the size and "handling" of MS mice. Actually my Intellimouse Explorer didn't even fail, it just started to look ugly, because the shiny grey plastic got worn out. I think this won't happen with the Sidewinder mouse since it's matte black. Anyways, I went into a store and tested mice lying around, and the Sidewinder mouse handled just fine and I liked it better than e.g. Razors or Logitech mice.
The mouse has features like "a guaranteed gazillion left-clicks before the button breaks", and you can program macros for specific games (or any other program) that will only be active when the specific game is running. Never used that though

I just "programmed" the thumb buttons with something more useful than "forward" and "back" for browser usage (I think it's still set to "i" and "space" for opening inventory and jumping in
Lord of the Rings Online). Oh, and it has a button that opens the games window that is in Windows since Vista

It has 2000 DPI and is not just optical, but LAZOR, which feels pretty twitchy at first, but once you get used to it, it's great because you don't have to flail around the whole desk when moving the pointer. It also can lower the DPI via buttons when more careful movement is needed, I think I used that once in Gimp. Oh, and the scroll wheel (and thumb buttons) is metal and actually feels very nice. Actually the whole mouse feels nice, it's pretty heavy, sturdy and has a great "this is a quality tool" feel about it, as stupid as that may sound.
This is all not really worth blowing 60€ on, though, because cheaper mice will do the job just fine, too. I just 1) had the money to blow on it and 2) like how it looks and feels. I wouldn't go back to a mouse with lower DPI, though.
