I read the whole article and various other similar articles and got a question: I would like to ask what are some brands you have had good experience with and what to stay away from. And do you have any recommendations for a good supplier. I don't have a lot of experiance with VFD's so a good supplier is important. Basically I know there's two major suppliers: automationdirect.com and http://www.famaga.com. I don't know which one to choose. Can someone help me out with this?
