Back in the ITOG (Isuzu Trooper Owners Guild) days Calmini was about the only show in town. Their quality was a mixed bag, some stuff good, some stuff needed improvement. As Maugan said, Darlington and Independant came into existence due to an opportunity to do a better job. Much like StinkyFab is coming into the Isuzu scene as well.

Hopefully those who have specific experience with the Calmini lift will chime in on this thread, but you may also want to get the opinions of the Isuzu folk over at the PlanetIsuzoo forums as there's a lot of installed Calmini lifts there.
