Since November 2008, I've been using the Canon HV30, a high-definition (HD) camcorder. This unit is tape-based. I'm still hopeful there will be a hard disk drive (HDD) model that actually does what I need it to do, but they still lack quality and external microphone inputs that are available on tape-based camcorders.

It's in the $600 range now and will no doubt drop as the next model release occurs. As always, I recommend getting a spare battery, and by tape by the 5-pack.  While this camera has HD capibility, your CE clientele may not need it yet. The camera does work very well in SD (standard definition) just fine. If you plan to use HD, then purchase HD mini-DV cassettes (DVC). The cost more than SD. So only buy them if you are planning to shoot in HD.
