Quoted from dozer1:Big Wheels and 55 bucks. Might want to run a strap around the pin a time or two, but works great and has many uses. http://www.harborfreight.com/700-lb-capacity-bigfoot-hand-truck-62974.html
Ditto on this, great helper for the price.
Moved 2 EMs including my HEAVY Jet Spin with this - great tires make maneuvering a breeze.
(Until you get that stair-climber, of course!)
