I just bought one and it was delivered today. I read a lot of reviews before committing to the purchase. It seems that the good out weighed the bad. I would never buy a pacesetter, but Airmass is a company of Holley and Holley has been one of the top names in automotive upgrades for a long time. I know they primarliy work on v-8's but the "knowledge of automotive" is what they bring to the table and so for $200 bills new on ebay I thought I'd give it a shot. I'll let you all know how it turns out.
