I saw various models of the decorative curb machines at Expo 2000. The Canadian model was electric powered and I didnt care for that one. The one that got my interest was something like the Lil Bubba and was from a company in Florida. All were easy to use and worked as directed. One of the machines laid curbing that allowed you to install lights (similar to the floor lights on a commercial airliner). One thing nice about Expo, was the price was $1,500.00 less at the show.
