Well my old air compressor is on its last leg, I seen an ad at Harbor Freight for a 6 gallon 150 PSI max compressor made by Central Pneumatic with coupon was just under a hundred bucks. I have no questions about the price as it is a good deal but I was wondering about quality. Has anyone used this product and are happy with it ?? What is everyone using to add air to our 110# PSI G614's ?? Anyone have something smaller that stores easily in the rig that has given them good results ?? Thanks very much, Bobby A
