That may have been the link I clicked on, very informative. Thank you for posting it. That is why I like this site so well, someone always post something in every article that I learn from. I think I'm going with the EP Integrations 2.0, not because it is better but I can afford and justify it. The AMP is by far the better choice but I'm not needing something that expensive for what I do.I posted that video about stored energy at the top of this page. Good info.
