I have a Kremlin rig with the excite gun, and they told me THEY were the best. Now I don't know who to believe.The best set up for on sight kitchen cabinet boxes, hands down... AAA pump. I use the C.A. Technologies 14:1 AAA with the bobcat set up and a 513 tip. I'm shooting CV mostly but have a pump for WB. No matter what it is, it comes out like butter, if you know what your doing that is.
