I am undecided about buying this machine since visiting the compucarve website and reading the reviews. I know that a lot of the problems experienced by those carvers were cause by sears. Others appeared to be doing something that the machine was not designed to do, and others seemed to have problems just making the machine work. But in all cases, the bad reviews were complete nightmares, and the good reviews said the machine was perfect. How can i make up my mind....HELP
