Pros -- reduced or eliminate bi-monthly CFE payments. Cons - if you can't afford the start up expense. Read the experience of the posters and I think you will find anyone that's been lakeside longer than heartbeat will tell you E2 Engergies (Bettina's the contact person) and E-Sun Energy. Find out what products they have available and google reviews of them. Also, talk to them. Ask them point blank questions. I'd go with the person who answered my questions clearly and frankly -- not the one who blabbered on for 20 minutes and couldn't give me a direct answer. And as to my experience -- exactly what El Salto said.
