Summary: Picked up one of these about a year after it's release and at a substantial savings vs. when it was first released. Looked at it's replacements the ux5 and ux7 and decided that this model probably fit in between them as the ux5 seemed to have lost features and the ux7 gained. As the price was far cheaper then either, I decided to take the plunge. Pros: Very solidly made.
Summary: I bought this camcorder few days back and this is one buy that iam not going to regret. In spite of some of the drawbacks, seeing yourself in HD gives you real high. The picture quality is awesome. Its like stack of 5-6 mega pixel images put together. I have infact paused the video at few places and taken screenshots of them. Lack of video editing tools is a drawback. Sony provides tools to convert H.264 to Mpeg. So that I can use the Mpeg files on Sony Vegas.
Summary: This is a very good camcorder with the main problem I noted being the DVD format giving only 30 minutes or so of recording in HD mode per disk. It is also a problem that only Blue-Ray DVD players can play back the DVD in HD mode. Even worse that it might destroy the disk if you use it on another player. Nevertheless, the price was good and I think Blue-Ray will be more affordable in the near future. Meanwhile, I can playback my video directly or send it to the computer.
Summary: I purchased the HDR-UX1 to go along with a new HD television. I pondered what to do get HD content to my TV (DirectTV, Dish, or cable). This camera has produced the only HD content that my set has seen as of yet, and I love the picture. The record time isn't really an issue for me because I shoot mostly scenery and such. However, if you want an HD camcorder for recording your kids basketball games or dance recitals, you should probably go with the HDD model.
Summary: There have already been a few well articulated reviews for this camcorder so I won't rehash the technical details of the camera. What I will do is caution you on over analyzing this product with what you read on the internet. Two sites, camcorderinfo.com and cnet.com do a pretty good job in their reviews of the HDR-UX1. But keep in mind that they are writing from the perspective of the tech junkie and/or semi-professional videographer.
