Ergonomic Mice

I currently have the regular two-button mouse cord and keyboard that came with my Dell. The mouse is not ergonomic at all, creaking and it is not the smoothest mouse in the world. The keyboard has soft keys and not a lot of feedback. Can you give me the best corded mice through here and you know where the keyboard where the keys have a better feedback. Definitely a laser mouse would be the best because there creaking possible.Logitech is mouse / keyboard package is of great feedback and pretty solid as far as I know or have experienced. Dell keyboard and mouse are cheap things that come standard with Dell and is really not something you want when you are away from your computer. Nobody can tell you what to buy. It's just your feeling that such Löf is one of the IT business to go and test, until you like one. BTW Dell parts are not expensive, the cheap Chinese goods with a logo, so do not expect anything good from them.
