I agree with P-worm, if you have just $1,000 to spend look seriously at the HV20. Some serious indie shooters are pimping it out and making some great images. I'm currently debating myself whether to go that route or to bite the bullet on the HVX200. I own a GL-2, and while it has a great lens and turns out some very nice colors, I just can't recommend anyone spend any amount of money on a new camera (or used) that isn't 24p. Also, the GL's sometimes have their play heads go bad which costs $500 to fix. This has happened to me, and while researching the problem, it looks like I'm not the only one.
On the flip side, I just shot something with a PD-170 (i know, no 24p, so sue me 😛) and to my eyes the image and color didn't compare to the Canons, although it did have a little better low light capability.
Also, realize, if you're using this for Doc work, you need an attachment to do good audio with XLR cables, the camera has no inputs for those itself. The DVX100 and the Sony's do however.
