Sam has been a Nikon guy for a while now, so I doubt he's talking about Canon lenses for his "dream lenses".

Anyway, is the Canon 17-85IS really that bad for barrel distortion at the wide end? The Nikon 18-70DX has moustache-like distortion at the wide end, not just barrel distortion, even though the zoom range is actually less than the Canon widezoom. I didn't use that Nikon lens all that much, but the moustache-like distortion did occasionally rear its ugly head in my photos.
I recently picked up a very lightly used, mint condition Nikon 17-55 f/2.8 DX locally off eBay for ~$820 net cost (after live.com cashback) -- just in time for a spring break family vacation to DC. Very nice lens though it's not w/out its own flaws. Works great as a walkaround for me, which I never really felt the same about the old 18-70DX -- always felt a need to bring along my 35 f/2 and usually also my 85 f/1.8 w/ that before, and even tried adding a (big-ish) Sigma 20 f/1.8 for the wide end, but that one is just too hefty to lug around (for a fixed prime) unless I'm fairly sure I'll use it.

As for the extra bit of tele range from 70 to 85mm (if you go for the 24-70L f/2.8), I wouldn't worry about that if I were you. Just zoom that extra bit w/ your feet instead -- or just crop a little bit more in post, if necessary. IMHO, 15mm is virtually nothing at the tele end.
