Looking for a device (12v) that comes in under £225 as this is the best deal I have been able to find so far.

I posted a link to one only a couple of days ago that was under £80 - although I've found a couple of reviews of it since that imply it's not that good.

Aha, the Firefox awesome bar worked....

The £225 one has an appalling frame-rate, more of a time-lapse recorder. Also, many of these devices have half the frame rate interlaced, so one which claims 30fps may only update every other line 30 times per second so is a sort of 15fps really.

I have bought similar stuff from www.inesun.com/ before, but not recently. They have an ebay store.
