DSLR Body advice Canon EOS 7d / 40d / 1100d

One thing about these older models no one mentioned which you should consider, older DSLR SUCK in low light!
When the lighting conditions are perfect these old cameras can produce picture just as good as any modern DSLR but indoor photography or in lower light its noise fest, picture very fast looses detail and you get very grainy picture.
o.

actually some of those old DSLR models do pretty good in low light (with a little "Neat Image" help)

old 18MP DSLR sensor (only 18 megapickels???)
ISO 6400

ISO 6400

Canon 18MP is old but not that old, dont forget it is still used in new cameras like the T3i and T5i
