Seems like we have two different conversationg going on here.
John,
Jamestown distributors sells Plexus MA300 with a disposable dispenser for $8.95. Pretty pricy for an ounce, but at least you dont need the gun.

I got a Proset Gun from Composite One for $92. The Plexus guns are only one chamber, they have to be cheaper than the Proset guns.
