i use a Powertow 3.5Hp model which works ok on the Acclaim. It does require regular fiddling to align properly, and the Acclaim is about as much plane as it's capable of moving.
I've used the Sidewinder on DA42's, and it is a very good product provided that:
You don't plan on moving the plane far
You don't have to deal with snow and ice.
Being able to take it along for the ride saved me a couple times when I'd taxied into one-way rows of planes. the DA42 is, like the long-body mooneys, very difficult to move by hand.
On snow and ice, there's really nothing I've found short of a tractor or truck that will work well. I scatter sand on my ramp for traction, and drop the air pressure in the power tow tire, but haven't yet resorted to snow chains. This time of year, I'm envious of your FXE location!
