I'll wade in with my movers. When I started doing out door shows I bought a "Handtruck " from Sears.1973.
This is the most versetile tool in my garden. When I am going deep into the borders on narrow paths I add a large plastic storage tub.
If you are doing a lot of moving and need a deeper platform for large planters over 18 inches I would suggest a Magliner. These are used to deliver beer,they are light weight and snal into four wheels.
