I thought that this was worth sharing - the 5D FF has gotten down to a little under $2600 over the past year, but I just saw a kit at B&H with the excellent 24-105 f4L IS (always on my 30D) where the price is $3329 for the combination, which purchased separately would be around $3600 - given the $1059 price of the lens. Now you can figure any number of combinations on each item to achieve that price, $150 off each, etc., but it seemed a nice package discount and I thought I'd pass it along.
