I'v been scoping out threads about it and decided to purchase it and installed it a week ago or so.
For $20's it is definately worth it and a necessity I would suggest. It gives you back some normal clutch operation yet it doesn't quite fix the issue completely although better than the stock spring. The clutch still grabs at the top pedal height, and there is only a milimeter of clutch grab giving you no play within the engagement/disengagement point, thus not letting you feel the clutch.
I would recommend the AJS (forgot manufacturer name) pedal assembly if the statements are true that it brings all the normal clutch operations back to the car and you have money to burn.
Just my two cents
