Underdrive Pully? Worth It? (archive)

Does anyone have one of these installed? is it worth it? how do they increase performance (hp/torque)? I have a 1998 2.8 and am looking into performance upgrades that are an alternative to the $5/6K supercharger/turbo upgrades. I've already done the intake/chip. Think I'm going to do an exhaust next, but what else would be a good idea for a boost without setbacks? I am aware that the exhaust isnt really a performance booster, but something i want to do.

My real question of course is about the pully. Should this be the next upgrade?
