The blade on my Haeksel electric chipper/shredder broke. Does anyone know where replacement parts can be obtained in the U.S.?

Also, does anyone know of other manufacturers who make small household ELECTRIC lawn and garden chippers/shredders? I'm not interested in the gasoline engine-powered models - they are too powerful for what I need. Web sites, 800 numbers, anything at all would be appreciated. I live in Dallas, Texas.
