I recently bought this to use as my ZoomCam. It works really well, and you can get batteries on ebay for under $20. for large capacity... I can get like 3 hours record time with one battery at 1080HD.
Refurbished Sony Full HD 8GB Flash Memory Handycam Camcorder HDRCX210 B 027242842175 | eBay
I was using a HDR-SR1. Which I had a wide angle lens for, I did a demo video quality test between the two cameras, (with the wide angle on the SR1).
Here is the HDR-SR1
And here is the new HDR-CX210B, with the standard lens. (little wider than my old camera, but not as wide as the wide angle lens on it).
Personally, I stick with Sony camcorders, as I've looked at tons and the quality of the sony steadycam is the best I have seen.
The sound on the HDR-SR1 is unreal, it records in 5.1 surround sound and does a great job. Plus it has a stereo input if you want to go from the soundboard. Limitation was the size of the hard drive, mine was a 30 gig. Which would be plenty for a church service.
The CX210 sounds decent, but I was spoiled by my SR1...
