I am interested in Real Green as well. But, I can't get anyone to help me. I sent an email, and it was returned because of a full inbox or something.
Then, I called and requested information. They seemed put out to be answering the phone and questions. The guy said he would send me a packet of information. And, you guessed it, he never did.
Hard for me to drop $5-6K on a product which is represented in that fashion.
If anyone from Real Green is reading. feel free to contact me.
