At those prices you'll soon find the lenses they are bundling won't be up to much. I found that, when I bought my 350D I got a cheap Canon 90-300mm lens. I can see just how bad it is now I've got a decent L series lens, even if that is only up to 200mm, I have a 1.4 extender for it.
The kit lens is okay, but again you'll see a very noticable improvement with a higher quality lens.
