Chony,

S910 all the way! Out of town is not CH and the 910 will be plenty. That's what I did for years, had a main one for local jobs and a simpler one for out of town. And in those days the differences were huge between the flagship and the portable. Not so with the 910 which is very very very smimilar to the T3 in many many ways.

Go for it.

Also, shop around. they can be had for under ~$1,400 if you shop well.

Good luck!
