Compushift Mini for 46RH

I've got a 46RH behind an early HEMI in a little hot rod I'm building. I've been looking at the Compushift Mini to control the overdrive and lockup.

I was wondering if anybody has any first hand knowledge of the unit and how you like it.

Did you end up with one of these? I'm looking to do the same thing for my 57 desoto.
