I'm looking to buy a entry level DSLR. I'm torn between a Nikon D40 or Canon Rebel. I'm concerned which one has better image quality. ik the canon has more MP, but it seems like the nikon has a better sensor, and 6.1 MP is definitly enough. I'm on a budget too so what are the pros and cons of each, or what are some other good options in that price range.
