the original all Automag Tournament team called "DAMAGE INC." of New Jersey (who use to play at the old South Hackensack indoor field) from the late 80's and early 90's came by the shop recently. He brought in his old 68 Classic from his playing days and threatened to take me out in the back and light me up with it.
I have never seen a marker that old yet still performing flawlessly. He kept it very clean but the marker hasn't seen the light of day in about six to seven years. After changing all the o-rings, oiling it up and gassing it up, he proceeded to rip on it. Damn he was quick.
I can't think of any other marker out there that can match up with a 'Mag on the basis of durability and longevity...can you?
