Can you tell me where I can get the ep4000 for $200. I also have a 13w7 sitting around and would like to power it with an ep4000. I will be building an enclosure in the basement ceiling between the joists and it will be vented into the family room above through the floor. This will take up virtually no real usable space but I can make any size enclosure that I want. I could do a 14in X 10in X 33ft long enclosure if I wanted to.
