Thanks for the suggestions, should probably have added to my op that I'm also looking for something light. I've had DMR pedals before and from what I recall they are solid but a little heavy.
I've been scouring various places and there are a few rock bros or clones of them on ebay at very low prices. Many claim to have 3 or 4 bearings per pedal. Having used crank bros a lot for clipless (why are they called this by the way as you have to clip in to them, assume toe clips??) and they have tiny bearings so do wear fast.
I'm an advocate of buying the right tool for the job and also buy cheap, buy twice. Are these cheaper pedals a false economy?
I do like the look of the crank bros 50/50 and would keep it in the family so to speak with the mallets, candy and egg beaters on other builds, but suspect the bearing situation to be the same on these.
