SlideControl jQuery Plugin allows you to easily make custom sliders for range inputs. You can set the speed, which controls the speed of the animation for a slider reszing. You can also set the LowerBound and UpperBound, which is the minimum and maximum amount the slider can be set to.

The CSS file included should be pretty straight-forward. You can change the look of your slide controllers in there from background color to size to how the handle looks. Just take a look around and it should be pretty easy to make changes.
