Anyone have or used one? I never even heard of one 'til I was looking for a grease gun on Ebay and ran across them. Some of them can either be operated by an air hose or still be manually operated. Kicker is, they are about inline with manual hand pump grease guns, as far as cost goes. At least the ones I've been seeing on Ebay are. Whatcha think?? Good? bad?
