I've got some nalini ones which are pretty good, and stay up well, although I've found that the grippers can get uncomfortable if I wear them for a long time. Much as I hate to admit it, I tried out Jim's assos ones and they're great. No gripper on the top, but they stay up fine under Lycra, and it means they are super comfy. I also like the assos knee warmers I've got, although the giordana ones are great too.
