Please help..any way you can... I just know I want a slr, and a digital, can you tell me maybe a...

brand annnd w/e else there is to know?

Thanks so much for your help...

Nikon is probably the most common digital SLR camera brand...we got the DX40, however, it's the lower end model.

Picture quality was the best (seemingly) from reading a ton of reviews, etc. Only one person we know who has an SLR has a different brand, and he has a cannon SLR.

I have a Cannon Rebel XT, one of the lightest in the market and also should be pretty affordable now, as it's an older model. I'm sure there are newer Rebel models out there now. They are great
