Here is a GREAT one on ebay !
An Original Centuri Mini-Max Hustler, NIB !
It just went over my spending limit though......
I saw an Aero-Dart go for over 900.00 a few years back....
This one is more rare than that....in pristine condition to boot !
The seller does not seem to be a "rocket" person....checked their past sales & saw no rockets.
I doubt if they have a clue as to how rare the item they are selling really is.
