Amando, I think Alexandre is expressing excitement about having discussions on the steadicam forum. "I'm so excited I can't wait" is so common in the US I didn't give it a second thought. Out of context though, it totally looks like he's saying he's too busy for us!
Thomas, The Archer 2 only comes with a G-50 now-a-days, if buying new.
Alexandre, there should be plenty of literature about the Archer 2 on the Tiffen website and elsewhere. I assume you are worried about missing out on something by getting the Archer 1 you are looking at. I don't know the specific differences, other than the obvious physical shape/portability. The power ports may be slightly different, or at least some of them. There may be some 2pin Lemo 12v ports on the Archer that will be 3pin Lemo 12/24v on the Archer 2. Speaking of, is the Archer 12v only? That may be different.
Good luck, maybe someone more familiar with an Archer will chime in, though I bet there is information if you do a search here on the forum. |-)~
