Recording FPV video feed

Does anyone know of a DVR that can record a PAL/NTSC video signal onto an SD card? My current setup is using my laptop to record but it is bulky to carry!

We sell a FPV monitor that has a DVR built in so you can record onto SD card-

But if you just want the DVR on its own you can get them from Ebay. I have not used the one below so cant say how good/bad it is. All I can say is try search for general DVR, as I found if you put FPV into the search you get the same things but they cost abit more.
