I picked up a JVC HD110. Huge issues with capturing with Mac, but I now have a work around, it is a Focus Enhancements hard drive.. situation solved. I personally question the 1080i format anyway. 720p at 24fps is good. 1080p at 24fps is better. There are some new Sony's coming through soon that are going to be 24p as well that might be in the $5,000 range. The Panasonic HVX200 is great, but it's still pricy with the P2 cards. Have you thought about a Panasonic DVX100B and shoot 24p widescreen? Another option is the Canon XHA1 is highly thought of. It has a 24f (from 60i source that is a good mimic of true 24p)
I like the 24p since DVD's, HD-DVD's and BlueRay are all 60i but recognize a 23.97 pull down and look far better to my eyes from a 24p source than a 60i source. But it all depends upon your subject matter and of course what DVD or HD-DVD/BlueRay encoder you are using. Some shows like Ghost Hunters and American Choppers shoot Panasonic DVCPRO-HD at 720p at 30fps so it makes a nice 60i for Discovery Channel HD. But I doubt it makes the best SD-DVD and HD-DVD/BlueRay's for later sale. But they have access to post production houses with $10,000 DVD encoder programs.
regardless, dvxuser.com and dvinfo.net are good places for info and opinions, and hopefully some usefull facts.
