www.ebay.com and do a search for 'small boat dolly.' They have a $150 galvanized steel, and a $200 stainless steel small boat dolly that is somewhat similar to the $450 aluminum Seitech boat dollies used for moving small sailboats by hand.
Plus, one does not have to drive to Stow, Massachusetts and back, to check it out ...... is brand new ...... and it's a returnable Ebay item.
