I think LightHound is currently out of the E2C made by Doug Speck though they have a couple of other models available. Doug Speck has a web site for his UBH which has an email address if you want to contact him.
There's also another current thread where Doug Speck has posted. Maybe you can PM him as well.
XenonM3,
Glad I was able to help. I'm hoping to get an E2C myself. Lighthound had them in stock last month, but unfortunately, I had no $$$. Now I see they're out of stock.
Did you talk to John from Lighthound? Did he say he was no longer going to be carrying DSpeck's E2C?
