Angus in Texas.....What makes these bettter than the pneumatic units is the fact that you dont have to mess with a compressor or hoses, any where a man can get to the driver can get to, we all have ran into areas that have difficult access. Also, the less expensive drivers that run off of the smaller air-compressors do not have nearly the driving capacity or the BPM (blows per minute) of this driver to include the propane powered driver that is on the market. The capability of this driver equals that of the larger pneumatic drivers that require a larger tow behind compressor. If you have driven as many post as I have using a tow - behind compressor and numerous lengths of hose patched together while running into numerous areas that you cant reach with your hoses, you will love this driver. You just pick it up and go. I bought one from the original manafacturer in Australia, took a chance on it and LOVED it. Liked it so much I sold my house, took all my available cash and bought the US distrubution rights along with a partner. Now ya gotta admit, how many products have you ran into over the years that you liked so much that you would be willing to take that risk for? As for letting someone try it out and post a report on this board, I believe in this driver so much, I would be willing to put my money where my mouth is and entertain that idea. Thanks!
