If you're considering wheel dollies, you may find yourself tempted to snag some from your local car-parts store for the convenience and price. Do NOT, under any circumstance, buy these ACDelco car dollies.: http://www.oreillyauto.com/site/c/d...=Search_wheel dolly_-1_-1&keyword=wheel dolly The casters are CR@P, and pretty much make them some pretty paperweights, unless you want to spend a bunch on some decent casters so they'll work the way they should. If you want an exercise in hernia-creation, go for it, and see how much luck you have pushing a car around on 'em. In contrast to the above, these work great, and being aluminum, they're that much easier to handle. I opted for the upgraded casters with the wheel locks. Shipping was fast, too, at least to a state away. http://www.car-dolly.com/
