Who uses a motorized tug?

[mshac]

I find myself unable to effectively move my 337 by myself. My hangar requires a 180 degree "Y" turn to get out. The concrete is slightly slanted away from the hangar for drainage, but that little bit of incline/decline makes it hard to move the plane. I usually have my son with me (plays high school football) who makes it easy, but when I'm alone I could sure use some type of electric or gas tug. There are so many different designs on the market. What do you guys use?

On another note, where do you push? Wing Struts? Nose cowling? Prop? Lower part of horizontal stabilizer? We've been using the strut but I'm worried we're gonna crack the cover.
