I just did some looking at the gas flush option on the Henkelman, Sammic and Minipack.
Henkelman charges ~$212 for the gas flush option. It comes standard on the Sammic S series and the cost is close to the same as the T series (which is without gas flush).
On the Minipack, gas flush is a $625 option on a new machine! So their add-on kit is the same price as when ordered new with a machine. I wonder what the kit contains to make it nearly 3 times the cost of the Henkelman?
How would you rate these three units? I know all have Busch pumps, so they are even there. How would you rate the other items? (overall construction, user controls, ease of use etc).
