Best online prices for Canon lenses

About to get a 24-105/L. So far $1549 is the price to beat from dirtcheap. Highest price $1779, median $1691. Anyone know of a better price, although that's a good deal.
Of course, I should just say I've bought it then there will be 5 posts telling me where I could have got it for $100 less
