Ok, I like the Canons and I think its between these two (today, anyway). I know the 20 is no longer produced and soon enough the 30 will be there with the 40 out now. Would I be at a disadvantage to choose the 20 over the 30 for technological reasons? Does the 30 have improvements that make it more desirable? I think for now, Im just going to pick up one of these second hand with the kit lense, just to see if Im going to enjoy photography at all. I figure the 30 might have a better resale value if I should choose to resell later. If I do in fact enjoy it, I can pick up a better lense later. Ive found a few 30s with the 28-135, and thats getting favorable reviews. Anyway, 20D or 30D?
