sup, I was hoping to get an AutoX cam (http://www.autoxcam.com) but my miniDV camera doesnt have AV-in, so i was wondering whats the cheapest camera out there that has the AV-in capability. Thank you.

I was lookin into this too.

I need RCA (analogue) in as well.

I was able to use, get this: a Dazzle Hollywood DV Bridge hooked to a power converter in the car. Mobile computer equip. Hooked my Ogirional Canon Optura via Firewire to the DV Bridge to the helmet cam.

Not as easy as a mini cam but it worked.

By AV in I guess you mean analogue in, right?
I used a Canon ZR40 that cost me around $400 a year ago. Works great.

Does this mean this camera has AV in?:

A/V Dubbing Yes, Audio Dub in 12-bit Mode (SP Mode with Optional Remote)
Line-In Recording No
Inputs 1x IEEE-1394 (4-pin)

The A/V dubbing feature isn't really a guarantee of AV input in the way you're thinking about.

The Canon ZR80 is now $399 list. That's the least expensive or close to it anyway. And it does have AV input. Hope this helps,
