Which DSLR To Purchase?

[AlexMichael]

Hello everyone. The top three cameras that I have in mind are: Canon 300d, XTI, XSI, and the 20d. I plan on taking photos of sports, candids and portraits(both day and night). I'm familiar with Canon DSLR(used the XSI in digital photography class). I've used the XSI indoors, but I don't know how it preforms while taking action shots at night. Also, I've done research on the 20d and found out it'll be great for action shots at night. Which of these three cameras would you recommend to me that covers the photography I want to do? Please feel free to suggest other cameras. My budget is $250 - $550 and I will be buying a used camera. All posts are well appreciated

I havn't used any of the cameras (I shoot with the XT 350D), 40D and 5D)
However if you can get a good one I would go with the 20D mainly because of the higher frame rate, the ability to shootat ISO 3200, and better erganomics.

For action shots at night, in available light, you will need fast lenses (at least F2.8 and preferably F2), be sure to budget for them.

Have you given any thought to what lens(es) you'd like to use with those cameras? Since you're buying used, I'd say I'd rather flip a coin on the body if you find a package deal that includes a decent lens. At $250 - $550, though, it's going to be tough to cover all your needs. A 20D with a 50mm f/1.8 lens would be good for portraits and candids, but it's not as versatile as you'll probably want for sports photography.
