That Dorman CV boot installation tool is starting to sound like a good deal at $150 bucks. Appears to do the same exact thing as the Astoria flexx gun, but at almost half the price.

I'm torn between buying that gun and doing my own vs having them done locally for $80 bucks apiece. Looks like it would be downright easy with the gun.
I'm guessing the Dorman gun could be used with the Astoria boots. I could have a CV party at some point. Been wanting to have an informal GTG over here anyway. But we'd have to order pizza or cook burgers. I don't do much else, and the wife ain't exactly into this "thing"......
