T2i vs 7D?

Any suggestions here?  The “specs” are really similar in numbers, but does that really translate to performance?  Both cameras have a 1.6x crop factor (no cropping with the 5D MKII) and both shoot the same formats of video (the 5D now with the firmware update).  Though, something about the video quality just doesn’t add up. If you list almost exact specs for two different models, but the cost of one is nearly half the other: What corners were cut in the manufacturing process to make this possible?

Canon seems to really hang it’s marketing hat onto specs with the T2i.  They obviously set out to make a camera that could match up in a side-by-side-specification-comparisonwith the 7D and be somewhat comparible to the 5d MKII.  Is it a just a marketing scheme?  I have seen the video comparisons on vimeo and I am impressed with the quality of work my colleague Kevin is producing with his T2i. 

This point of this post is to start this discussion: 

• I know it’s less expensive, but is it worth paying more for the 7D or for that matter the 5D MKII?
• Is the superior low-light performance of the 7D warrant paying +$800 over the T2i?
• Does the supperior low-light performance of the 5D MKII plus the larger chip warrant the +$800 over the 7D?
• If you are considering the 5D MKII, should the 7D or T2i even be in the discussion?
