I'm looking into getting my first Digital SLR, and I'm hoping to not spend too much (as little as possible really), but I want a good camera. I've decided on a Canon Rebel because I like the simplicity, the price is right, and it seems to take great pictures. Now, I've been looking at getting a Rebel XT on Amazon or Ebay for in the $400 - $450 range, and a Rebel XS would would be roughly $500+. The Rebel XT seems great, but I'm a little unsure about a few things. It has a small LCD screen (1.8 inch), and a digital read-out above it. Do you guys see the digital read-out as positive, or would it be better to have a bigger screen with all the information on it? Also, I know this sounds like a stupid question, but with a Digital SLR, do you exclusively use the eye-piece when taking pictures, or do you use the LCD screen? (My current camera's digital eye-piece has a ridiculously low resolution, so I cant use it). I believe the two cameras take comparable pictures, and the extra two megapixels in the XS isn't worth the extra money to me. What do you guys think? Are there other features that make the XS worth it?

Any help would be much appreciated,
