However, to me, the more important decision maker would be Panasonic's discontinuation of replacement parts. I have a DVX with only 100 hours that is useless because I can't get the parts to fix it.
You know I've read your posts about about Panasonic discontinuing parts but I just don't see how that can be true with so many DVX's still in use as well as being still in production. Are you sure you are getting the correct information from whomever is repairing your camera? Also have you tried contacting Panasonic directly or other certified repair centers?
Now I won't deny that the DVX is a delicate camera. Mine took a dive and hasn't been the same since so I'm looking at replacing it.
If you look at this from an investment standpoint, IMO, the HDV camera will hold it value better than the SD cam.
I don't quite agree. Sure if you need to deliver HD now then it makes sense to spend the $900 more. However unless you're doing broadcast then you're probably not going to be delivering HD for another couple of years. By then no doubt there will be better HD cameras and solid state recording will be mature and affordable enough to finally rid of tapes. I would say that by saving the $900 now and instead invest in other aspects of your business that could yield a higher return on investment.
