As a Canon owner I'll throw in my 1 cents worth.
If you have a narrow IPD with a big nose or wear glasses when viewing try before you buy. Clearance can be tight.
The Canon performs optically slightly better with the IS off. If the IS were to fail it's not the end of the world.
Swarovski are sold by specialist dealers and it's hard to get a substantial discount. I tried and failed to buy a SLC 8x56 recently.
Canon on the other hand, is carried by places who sell washing machines and computers and here in England you can get great deals if you keep your eyes open !
I used to run an arbitrage business selling prestige German brands into the US in situations where the official US importers jacked the prices up to unrealistic levels.
