Hello,
I just purchased a 20D with the 18-55 lens during the tripple rebate period. I bought mine from buydig for @1250 before any rebates...I also bought 2 additional lenses to tripple the rebate value from B&H photo ( bhphotovideo )... the accessories were less money at B&H than buydig.
Both sites were well reviewed by other people and each site had delivery to my home within 2-3 days of the orders...I checked each site out on bizrate , eopinions , and bbb (BetterBusinessBureau).
After the rebates come through I will have spent less money for the Canon 20D w/lens, a Canon 28-135 IS USM, and a Canon 50mm Macro than if I just purchased just the camera at either CircuitCity or BestBuy. Because of the rebate I changed from getting the Rebel XT to the 20D.
Where ever you get yours from you need to research the site and have a little bit of a good feeling about them as well.
Mike
