[font color=\'#000000\']I'll chime in as well. I have over 1000 frames through my new 20D and it works great. It is much faster than the 10D - instant on, instant review, 5 FPS, it writes to the card much faster, it's lighter, has fewer parts (almost 100 they say) and costs the same as the 10D did last month.
Plus, you have the benefit of several new EF-S lenses that will not work on the 10D including the much anticipated 10-22mm, ultra wide angle.
Regarding prints - I've gone 20"x30" with a 10D file (good clean image, taken with "L" glass) and it is tack sharp. I would assume that with a clear, sharp file, you could go 24"x36" and still have outstanding print quality with the 20D. That's poster sized.
It's a no-brainer - go grab yourself a 20D!
