I've just won a Canon EOS 450D with EF-S 18-55mm IS & EF-S 55-250mm IS. Only a couple of weeks ago I bought an Olympus E510 with twin lense kit Zuiko 14-42 & 40-150 after considering quite a number of alternatives.
I am new to SLR's and am on a steep learning curve. If I had the budget at the time I may well have bought the 450D or indeed the E520. Now I have to decide whether to sell the brand new Canon or the slightly used Olympus. A great problem to have I know! Can anyone offer some advise to help me make up my mind?
