Hi Wayne,
A few things I've noticed using both boxes; TC input on the SB-T is 1/8" mini vs. lemo on the Lockit, and syncing the Lockit is marginally faster than the SB-T- just plug in and unplug, jammed. The SB-T requires you plug in, wait for flashing lights to indicate sync, then unplug. That being said, I like both boxes...but I like the Lockit a little more.
