[font color=\'#000000\']You really need to decide what kind of camera you want. The A1/A2 is an all-in-one, is small and relatively light. The 300D is larger, heavier (once you add lenses), and is certainly going to cost more long-term as you add more lenses. The 300D is more flexible in terms of what you can add to it (you can add any EF lens Canon makes that you can afford), and will give you slightly better images (and much better at ISO 400 or above).
My conclusion was that I didn't want to carry around the weight of the DSLR with the lenses I would want. So I bought an A2.
