I have a 20D I bought 2 years ago and I paid $500 for it. You did really good getting it for basically $300. I love the camera, and it does more than I can use still! I'm *still* learning how to use it to full potential.
I would recommend a different lens. The 18-55 is a kit lens, and you won't read alot of stellar reviews about it.
At Christmas I picked up a Tamron 18-200 that does everything I need.
Nobody knows why Pauldun is such an ass. I think he does it for attention personally.
I'll gladly post some of the pics I've taken with it if you want to see what kinda quality you can get from it.
