I'm looking to purchase my first camcorder. I've narrow my choices to the JVC GR-DVL920, the Sony DCR TRV25, or the Panasonic PV-DV851. I'm looking for a reliable unit which real good performance. I also liked the Canon ZR50 but i've been scared away from it from hearing alot of people complaining about the loud motor noise coming through on playback. Any one have any input on these models.
