I bought a tool caddy at Harbor Freight. It has wheels and an extendable handle, like luggage. My husband cut a small piece of plywood to put in the bottom of the bag and it works great. Think I paid all of $25.00 for it. I could not stomach the cost of a Tutto bag ($300!!!!). If you're just taking to to classes and retreats, I don't see why you'd need the outer frame that the Tuttos apparently have.
