I ordered the DVC250 on the internet, feeling that if it didn't work out I could return it. I have to say I am very pleased. It stayed set up in my bedroom for two weeks. I went to Home Depot and bought a "garden wagen" with large baloon tires and built a frame to attach the tripod and crane. Now, instead of having to drive up to the location and being limited to where I can use it, with the wagen I have the mobility. The crane is easy to assemble and works like a dream. I am very happy with it.
