All I know is I won't be buying Giottos again. Not just one leg but two have come out in my hand when extending them. Because they used a cheap plastic inner lock deal that evidently easily snaps. I put it back together then used electrical tape on those joints, never to be used again. The ones that haven't failed, well even after tightening the joint screws to the point of almost breaking when clamping down...they still don't stay out and often slide down/in. Not real thrilled with the ballhead I got for it either. Horizontal spin axis knob is all or nothing and damn hard to get tight so it stays. The whole legs coming apart in my hand twice now over a dumb piece of plastic has really turned me off. You look at this piece and how it goes together and what it has to do/support and it's just a real head scratcher they have this plastic inner piece like it is. It was just a bit over $300 for the legs and head so not an expensive route exactly but certainly not the cheapest $50 free with camera tripod deal either. It should take some work to have the tripod legs come apart/out in your hand, not casually extending them down on two different occasions.
Sorry can't say what to get, but figured I'd say what I'm not getting next time around.
