Totally non-DBS, but I'm a relative novice at photography (at least for what I'm thinking about). Has anyone here used or bought the new Canon Digital Rebel SLR (EOS-300D)? I've been using an Olympus 3 megapixel digicam for sports photography, but it falls far short of what I need. I'm wondering if the 300D is too "cut down" and I really need the extra $$ for the EOS-10D. I'm shooting basketball games and auto races, and need to upgrade. I've read the reviews at the usual places, and played a bit with the 300D at the local Circuit City, but it's only confused me more, not made it any clearer.
