WOW! You are going to love that lens!
I don't blame you for a second for not wanting to spend serious dollars on an EF-S lens. On one hand, the demise of crop bodies has been predicted since they first arrived, and EF-S lenses are always going to work on crop bodies. On the other hand, there is something to be said for future-proofing your purchases and that is one nice lens!
Are you buying a good UV filter to go with it, (like the B+W UV MRC)?
We had a brief discussion of this over on CR about the rebate lenses. Something is definitely strange going on over at Amazon, not only do they
not have stock on many Canon lenses but sometimes they don't even list themselves as a seller. This entices their "affiliates" to charge ticket-scalper pricing. Check out the
Amazon link for the 5D MkII w/ 24-105 f/4L to see what I'm talking about; $4,500 from Pavilion where $3500 is Amazon's "normal" price!
Anyway, as of tonight B&H has stock on most of the glass your list; I'd guess Adorama would too:
EF 16-35mm f/2.8L II USM
EF 70-200mm f/4 L IS USM
EF 24-70mm f/2.8L USM
EF 70-200mm f/2.8L IS USM
EF-S 10-22mm f/3.5-4.5 USM
Apropos of nuthin', I really covet that EF 70-200mm f/2.8L IS USM in the worst way. I hope they are still in stock in mid-July before the rebates expire (and that I can raise some money by then).
