I agree...the SLR is *always* better. If you get an EOS 300 then start saving for a Canon digital SLR...or get a Nikon film SLR and then save for a Nikon DSLR.
Film does have good quality...certainly better than most/all point & shoot digital cameras like the A70. However, if you goal is to have digital files...scanning film can be expensive or problematic.
Think about the costs of developing film...it can add up quickly...but it would probably take a year or more to make up the cost difference between a film SLR and a DSLR.
