i felt lucky and happy with my canon 550D.
used to have the rush of shooting when i got hold of my canon 550D until when i realized, save shutter life, dont anyhow snap.
and nowadays what i do is, spot for nice angles, nice locations, then fire. my 550D serves me well and the picture quality is good. it's all in the lens. and i felt that there are lots of rooms for me to improve and xplore on this dslr.
