I've recently purchased a cheap tripod from eBay and it is really flimsy. It isn't very sturdy at all. Can anyone recommend me a sturdy tripod? I see a lot advertised as lightweight but I feel they could end up being just as flimsy as the one I already have. I don't mind too much about the weight as I won't be carrying it around much. Im looking to spend up to £50 for something half decent.
