For those who drive manuals and would like to upgrade your shift knob to a weighted one be sure to check out Raceseng. They make high quality products and they are made to order. Unfortunately they are going out of business and giving 40% off site wide. They have some weighted shift knobs which changed my shifting and driving experience dynamically.
I know some like lightweight shift knobs and they have some options as well in the clearance section.
Go to their site and check it out while supplies last. They shift knobs are made of stainless steel.

Here is the one I purchased with an extender and it was shipped to my door for $90 with everything I needed.
Shift Knob Name: The Slammer
Weight: 1.4lbs
The heaviest one they offer is Ashiko at 1.6lbs.
This the best mod I added to the car by far.
