I bought this E-Prance from Amazon.

I'd say that, with no other experiences, it's pretty awesome. It came with a 32Gb Micro SD card (the versions without the card were more expensive). It's takes more than 1080p video (2304x1296), 5 hours 20 minutes on a card, records your GPS and speed, records interior audio (not that great of quality), can auto-overwrite so you never have to empty the card, and you can program your license plate in. I've used it to record tons of video while driving, and it's everything you'd expect. I leave it on my work truck, plug it in every time I drive, and then shut it off every time I stop. The camera doesn't seem to mind baking in the sun, and seldom skips a beat.
I did have an issue with one of the power jacks though. The GPS antenna and the camera unit clip together. You can use the camera without the GPS if you want, and both pieces have a charging jack on them. When clipped together, plugging in the supplied USB Type-B cord to either jack charges the battery on the unit. Well, the jack on the GPS unit quit working for me. Perhaps due to the weird angles it's plugged in, or the stress from the dangling cord. I have the cord plugged into the camera body and it works great.
I'd totally buy this again. There's an option to auto-loop every five minutes, but I find it more reassuring to just fill the card during the week, and then wipe it clean each weekend if there's nothing to report.
Hopefully this helps!
