Yeah, so I just ordered a Lowepro Rezo 160. It's available for $35.99 at Amazon and B and H!
I'll do a review of it later maybe.
My cousin has a Rezo 170, and I like it, it's just a little too massive for me and my D40, so I got one size smaller.
Unfortunately though, he has the bag for a Canon XTi though. He fits that with a Tamron 28-250 on it, and he also fits a mid level Canon flash (the size of a SB-600) too, with a bit of finagling.
I'm probably just going to put my 35mm 1.8 and 18-135 in it, it should fit fine.
