Hi James, I am happy you like the DVD. The problem with cheap sets is they are often lightweight, the dollys are not very good shapes, you could reshape them as you see fit to suit the jobs you are doing.
I tend to buy cheap tools for things I don't do often and invest in quality tools if they are going to be used regularly.
Here is a link to a tool that you can put on a grinder and cut a bowl in a stump.

Just take care when using it!
