I looked at the ACME EZ tow dolly, liked it except the seller thought I should pay more than a new one, then found a Road Master and bought it for $1000. Used it one time and sold it for $1200, after selling the Jayco motor home and getting the new FR 5th wheel.
There are lots of very nice tow dollies on Craigslist for sale, year round, some cheap, some priced right and some priced high.
