Yes, I did. It was $350 or so, bought as a group buy of ten or so over at Spyderclub.com back in the early 2000s. It came with three nozzles, a bunch of ferrules, and aluminum tubing which was easy to bend by hand or make tight curves with a brake line bender.
In the demise of my first car, the cable was pulled and contents emptied. I currently have it at a local fire supply company for a refill/pressure test. It is a 5lb. CO2 bottle, rated for very high pressure, more than adequate for the low pressure Halon 1211(I think) that was in it. Today they use Halotron, non-destructive to the ozone layer.
When I get it refilled, I'll be aiming it at only the carbs. It will be a cable-pull system, as before, so not automatic like the ones you guys are purchasing.
