I've just bought this camcorder from my local Currys store, price elsewhere ranges from £250 on amazon to close to £400. It seems like a decent bit of kit, it got good to average reviews at the £350 price point. It's standard resolution and gets good quality from the relatively low megapixel image sensor and has optical image stabilisation and a 32x optical zoom. It records onto a 30 gig hard disc or to SD memory cards (supports the newer type so should work with 32 gig cards). If you plug it into a computer you can drag the mpeg-2 video files straight off without software so it works with my linux boxes and should work fine with macs and anything else that supports USB storage devices. No in-built light and no sound inputs or video inputs.
The chap in Currys (Yeovil) let me take an SD card in, shoot some video onto it, and then take that home for review, I did that for a few camcorders and the quality of this was better than the nearest rival, a Samsung that only recorded onto SD and was only £30 less expensive. I went for the Panasonic in the end.
I've also just tested it with a universal power supply, and provided you have one that can output 7 or 8 volts at the correct polarity then it'll work, so you stand a good chance of it working with a car power adapter. The power jack is behind the battery though, so you can't recharge the battery at the same time as you run it from mains unless you use the provided PSU, which has an off-camera battery recharger built in. This was useful to me, as other makes like Sony and JVC tie you into using their specific power supplies.
