Well, I guess what I'm concerned about is that the 450 is a pretty new camera, with LCD panel and what have you, whereas the 900 comparatively older. The dealer with whom I spoke mentioned a whole kit, lens, viewfinder, power, etc. for a "comparable" price to the DSR, I think he even mentioned that he could get the dsr kit for 11k after the rebate. He did mention that the deck would be another 5-6k, so I'm not sure. What I like about the 450 is that I can use my existing deck, edit on my existing gear, and if I need to eventually uprez, there's always rental houses. Also, 3 hours per tape is pretty luxurious. I've normally used 120min DVCAM tapes in my 370, but I always know that possibility is there. The 900 is limited, I think, to 33 minutes, but if I'm even considering the eventual uprez, it does have double the color data. Weight is also a factor, I have some spine issues, so I'd like to err on the lighter side. I think the 450 is about the same as my 370, but I'm unsure. Anyway, I have a month or so to decide, before I'm out of the country with whatever I chose.
