I have had these for a few years but I have never used them. New at that time they were $3600 each and I paid $2500 each, so, a bargain at this price any way you want to look at it; $1500 each. They have been stored in a basement all this time. When I bought them one had been used once and the other 3 times. They are complete with all accessories and Co2 tank.
