Somewhere in the recesses of my memory I seem to recall (maybe falsely?). That, Powerlogix used to advertise a discounted upgrade path from one PL unit to the next. True/false? Does this still exist? Anyone try it? I only live about 1.5hrs from their office so it would be cool to think that in 3hrs I could have a 'newer/faster cube'. ------------------------------------- Gregory P.
