You can't have too many GP100s. I know - I tried. I'm kinda partial to the 3" and the 6" (oddly.) I'd grab a 1708 while they're still out there and available. That model was out of production for a couple of decades and who knows when or if they ever decide to make any more after this run is done.Thanks everyone for clearing it up. I have a 4 inch, but after seeing all of the nice 3 inch models on the forum, I think I need one of them too.
