Whoa, there's a lot there.
OK, first of all, I got it for pretty much all the reasons you listed. (American-made, first model, a bit more rare, high-quality construction, etc.)
Secondly, it has been refurbished and looks amazing. I'm pretty sure the switches have been replaced, and there might be other new parts as well.
I'm assuming that's why it cost so much. I posted a picture of it on the H6er thread if you want to take a look.
Maybe I shouldn't have said "barely-used" in my first comment since it's actually refurbished. I still think it was treated well though, because the case is barely worn at all. You can clean a case, but I don't think you can un-wear one to its original matte beauty.
...I'm very new to this, so don't expect me to know as much as you guys. I'm here to learn.
EDIT: You have published homebrews? I am honored to be in your presence, sir.
