I would shy away from EasyCap devices because there are so many cheap Chinese knockoffs you don't know if the one you buy is good or bad.
I've heard good things about Hauppauge and their video recording products. They even have an HD PVR, but it's around $200 and last I checked required some tricks to get working on Linux. Then you'll have to deal with the USB bandwidth being high enough for HD video.
