I've been thingking a lot on what camera to purchase. Ive been considering Cannon 500D, Nikkon D5000 and pentax KX. I've been surveying around and most of the shop owners has been telling me to get the Nikon and they can give me good offer on the nikon. Any advise from anyone out there? I'm quite a newbie thus not really that familiar on the detail technical aspects of the cameras. Thanks.
