Most RGDs are very happy to have someone come on and be a service center, they also will definitely sell you machines to keep in the store. Most Rainbows are sold by in home demos, but most service centers have at least one or two on hand to sell to someone that comes in and wants to buy one, or has an old one thats beyond repair and you sell them on trading up to the new model. When I get my own store I plan on trying to become a service center too, I really do love the Rainbow product and would enjoy being involved in taking care of the customers and their machines. I'd also LOVE to have a new one to sell as well, won't be my biggest mover, but any time I;d get a customer with severe allergies or the like and need a vac with excellent filtration, or someone that prefers not to have to buy bags or filters all the time I'd do a demo and try to sell them one.
