If you are looking for a camera to take high quality video for your own viewing, the Canon GL2 is an awesome unit. It is compact, lightweight, has a 20X optical zoom, and takes fantastic video.
If you are looking for a camera to use for producing TV quality footage.....the GL2 does not have the audio capabilities without adding aftermarket parts to accept twin, balanced XLR ports. The GL2 also is a 6 lux camera, meaning that you lose a LOT of filming time at first and last light.
For just a little more money, you can pick up a PD170(Sony). The PD170 has twin XLR ports onboard. The PD170 can also lay down quality footage a full 20-25 minutes sooner than the GL2 in the morning, and the same 20-25 minutes later in the evening.
Drawbacks to the PD170......bigger and heavier than the GL2, and only 12 X optical zoom. The 12X zoom is fine for almost all bowhunting applications, and you can pick up a 2.0X telephoto lens if you feel the need, taking you up to 24X optical zoom.
Audio quality on the PD170 is awesome, and can accept a shotgun mic, and a wireless mic right out of the box.
Another thought, as Rob mentioned, the older digital high 8mm Sony cams with 1/4 CCD heads, instead of the newer models with 1/5 and 1/6 CCD heads. The footage on some of the older digital 8`s can be fantastic. You will never get quality audio from one, but you can make it more than good enough for personal use.
I use all Sony cams.....1 HVR-Z1U, 1 PD-170, and 1 TRV-840 digital 8mm that I carry in my pack as a spare, just in case the big camera goes down. Knock on wood, no failures yet.
As far as seeing some footage...........Action Packed Outdoors volume #1, and possibly volume #2 coming in the spring of 2007.
