Welcome, and I must say, nice machine. I plan my next equipment purchase to be an X1120 model (same as yours without the cab) when I finally get back stateside. I've been reading "Would your wife notice if you got a new tractor?" thread, because I'm sure I'll be getting the "we don't really need that" speech.
Your 1100 with the cab looks great, but with my intended uses, I think the cab would be more of a hindrance, not to mention a substantial added cost. Enjoy the forum. I've gotten a lot of great info from it.
