Can someone tell me? I went to a local merchant shopping for an air comp. I found a nice Hitachi 2hp. twin tank (20gal) for around $350.00 they also only sell Senco nail guns due to many other brands breaking down these are the most reliable. They said that the comp. would handle this gun or even a framing gun around the house but if I were to use multiple guns off of this comp. I should upgrade. Does this make sense or is a Sears model the way to go with the big tank. Thanks.
