canon rebel t1i vs canon eos 5d

[bkv1997]

Need some help deciding to go with newer technology with smaller sensor or older technology with full frame.


canon rebel t1i
digic 4
Facial auto focus
15 mpixels

canon eos 5d
digic 2
Larger sensor
better constructed
12 mpixels

I know price also plays into it, but taking that out of the equation just interested in what others would choose and why.

Thanks for your help.
