GBC has AEM underdrive pulleys on sale for $135 shipped. The kit includes the accessory pulleys and new belts. Also, there is no need to worry about the longevity issues of before as the crank pully is not replaced. Certainly sounds like a good deal to me...

Removal of torsional vibration damper NOT necessary*
*IMPORTANT:
Vehicle manufacturers have thoroughly investigated the use of torsional vibration dampeners and conclude that their use significantly reduces NVH (noise, vibration and harshness). Furthermore, manufacturer and independent research shows that torsional vibration dampeners are critical to engine life where long-term use is intended. Removing the torsional vibration dampener from an engine can be highly detrimental to its long-term operation!
