If you are looking for a SD camera I would pick-up a Panasonic DVX100A. You can find them used on ebay for around $1,000.http://catalog.ebay.com/Panasonic-DV-PROLINE-AG-DVX100A-/43110237/r.html?_fcls=1
The 7D is an amazing video camera with it being used forcommercials, music videos, documentaries and maybe a futureLucasfilm.
If you are in the $1,800 price-range I would get a Canon 7D DSLR camera. Check out http://www.redrockmicro.com/dslr/index.html for rigs.
Looks good! Keep it up.
