JeDiBoYTJ,
Trying to get this back OT...
I don't know your background or current situation, but if you are going to shoot a movie that WILL end up getting xfered to film then HD should be a consideration. I would look at JVC's new HDV camera though, instead of Sony's, 'cause the JVC will do 24p.
Something else to consider (again, I don't know what you do & don't have), is spending the money on filters/lenses/adaptors for your current camera, audio equipment (good mic & boom pole), lights/lighting equipment, or other camera equipment (dolly & track, jib arm, steady-cam type device). I worked some guys on a short and they had a good, homemade dolly & track and jib. In Bruce Campbell's book "If Chins Could Kill" he talks about a lot of the homemade camera rigs used in "Evil Dead."

EDIT: About storage, what kind of HD are you looking to use? HDV, DVCPro50, HDCAM...? As the storage requirements for each can be different.
