Can you not get in on the B&H 60D deal ($899 for 60D+18-135 and a few other things)?
I would if only I could, but I live in Europe. So it's a no go. ATM that said set costs around 1000euro + 50euro rebate, that's good enough for me.
Thus dust sealing is more important to me, and in this category even the 60d should do ok (unless non-sealed lenses, esp. zooms which will attract dust and sand like a magnet).
Dust sealing is more than enough for me too. And I wouldn't also be afraid if I would be caught out even for a while under a slight drizzle.*according to the reviews, that is*
