Digital 35mm SLRs?

pipingguy asks: "Canon has released the first(?) 'low-priced' digital 35mm SLR with interchangeable lenses with the Digital Rebel. I've owned a few digital and non-digital cameras over the years (and am by no means a photography expert), and most annoying was the lack of manual zoom and focus, not to mention the barely-noticeable millisecond delay between button click and shutter closure. Can any owners of this and other digitals provide some opinions on how this new model compares to the more expensive digital 35mm's and typical $300 SLRs? Is it time to buy?"
