7D VS Rebel:
Go 7D for the following reasons:
better monitoring: t2i goes wonky when recording if using an HD monitor
better iso increments
better batteries
more 'pro' build quality
you can sell it after using it and it will hold more value.
Your other choice as of today is a 5d2 - better audio recording onboard now, now does 24p, and a higher MTF (it would appear) to hold more detail when looking very close. This is coming from a 7D Lover.
Re: shoulder rigs:
google gini rig. Or gini.1980 on eBay.
Lenses: get used manual focus nikkors or contax zeiss.
If you are REALLY SERIOUS about this movie Then email me directly about using a HotRod Cameras PL 7D and rent Cooke S4s, zeiss primes or red pro primes. I've got everything for a feature (mattebox,filters,rig) because I've done 3 on canon dslrs so far.
Real pro lenses make the biggest difference in handling.
Re: cards - doesn't matter between the 133x and 400x for these cameras. The 400x might download to your computer faster.

Seems to me you feel threatened by the T2i. Better everything even value? The T2i right now is actually selling more than what people paid for it. Second the T2i and 7d both use the same cropped sensor.
You can read any blog or review and basically find out that the T2i compares about 90+% equally as the 7D. The extra $700 would better be used on lenses or several other things regarding film making. Any new user would not buy the 7d over the T2i right now.
