Hi, all! I've been out of the FTA scene for a while (I was last active here in early 2006) and since then, obviously, a few things have changed. One seems to be that a lot of people have the Fortec Star Mercury II receiver. I glanced at the specs, but I can't see how it's really all that different from the Lifetime Classic NA, which is what I have. What is it about the Mercury II that everyone loves so much? Is it worth an upgrade? I see they're not very expensive.
