I use a T7 in my shop but like to carry my T4 out for smaller jobs. The handle is awkward and off center. Ken reported he carries his in a bowling ball bag. I looked for a bbb at W-mart and did not find one, but came across a 42 can rolling cooler for $30. I put an 8x8 box in the bottom for the wheel and the T4 sits on it. It even fits with the US105 in place. Pockets on the top and front hold additional stuff. Did I mention it rolls?
Clever, Steve. My bowling ball bag doesn't roll. (However, it is easily carried with either a strap or a shoulder strap.) I found the Brunswick single bowling ball bag at Dick's Sporting Goods.
Either method is inexpensive. One might invest in trying both.
