I recently bought a JVC SuperVHS-C camcorder off of Ebay
It was an impulse buy (got it for $1.99!) so thorough research was not part of the equation.
The only problem is that I can't find any record of JVC ever having produced this particular model. It's labeled a GR-SXM720. Google searches turn up nothing other than generic links for 3rd party accesories for it. JVC has no mention of it on their website. It looks identical to the JVC GR-SXM520U that they have in their archive section (pic below) except that the viewfinder on my camera is shorter. The Zoom control wheel on the top of the camera is labeled "VOL", which seems... curious. Perhaps this was common on JVC models.
I haven't done lots of testing. The camera only showed up yesterday. But it seems to be working normally. I recorded to a tape and played it back. The video out works. The charger worked. Unfortunately, the seller didn't include the DC-out cable so I can power the camera with the AC adapter. That little cable will cost me more than the camera itself. Here are some (blurry) pictures.
and the official GR-SXM520U
So is the 720 a legitimate JVC item? Why don't they list it on their website? Any information you can provide would be greatly appreciated.
