Operative word being "think", I think it'll be fine in build quality. All he reports I've heard talk about it having a sturdy build. Also it's a Nokia and I have NEVER had a Nokia phone break, I currently have a slider and I've used it for over a year, it slides just as well as when I got it (even though the phone has been smashed against the ground and various other objects).

I'm sure it'll be a fine messaging phone, though honestly if that's all you're looking for you're probably overshooting the mark a bit, and hence also paying more than you should.
