I just picked up a Sony PD-150 to start filming with. It is the predecessor to the now popular PD-170. They are practically identical. It is a very nice camera that is very easy to use and is great in low-light. The Canons have a better zoom, but unless you are looking at an XH-A1 they have some down sides that kept me from buying them.

You should check out the Hi-Tech Hunting Video and Photography Forum. A lot of good info there.
