There is also G/V--GEAR VENDORS OVERDRIVES-in CA.-800-999-9555--They've been around for awhile

Also American Overdrive--Art Carr was a distributor--Going back 10 or so years on this one-

They both seemed like reliable units--at the time I was looking to save wear and tear on my Hone-o-Drive unit, but installation required a little extra modifying to my floorpan in addition to what had already been modified by Motion------------So the bottom line is I never tried one of these units,but they are altrnatives---JoeG
