One thing - be careful about online dealers who offer prices that seem too good to be true. They usually are. In the US, there are reputable etailers like BHphotovideo and Buydig and Adorama. They usually sell for close to the same price. If you see somebody else selling the same item for 20 percent less, you should be cautious. Go to www.resellerratings.com
to make sure that they have good ratings from previous customers.
So, if you can get the Canon T3 for $410 US, even for body only, I am surprised. That camera is just coming out.
