I’ve got the PCS-4 which is excellent. ChainReaction do them for about £200 which makes it a bit pricey but the clamp is excellent and the thing will last longer than me. It is more of a permanent stand though, the legs just pivot closed rather than fold up, so if portability is needed, look at the PCS-10
I happen to have a PCS-10 in the house at the moment as I’m keeping it for a friend to give to her husband for Christmas. Obviously I haven’t used it, but have put it together and I have to say it does look a quality piece of kit
