Hi Dalex,
I recently got hold of a Vitruvian (aluminium) and am very happy with it. It's a neat tripod that comes with it's own good quality carry bag, a set of tools and an adaptor between 3/8" and 1/4" screw threads.
Like you, I too couldn't get hold of one at first. I ended up ringing DayMen and they told me that they received a batch for the release, but got caught out with the popularity of it and soon ran out. The girl there couldn't tell me when they would be getting any new stock in either. I tried a couple of places on Amazon who told me they had one/two in stock... order now to get them... only to take my order and write back saying they hadn't any and would I like to leave the order with them until they got one in... NO! Eventually it did pay off and I got mine for £190.00 including delivery.
The legs are very stiff to unfold and do lock into place on a kind of ratchet system. To raise them up again you have to pull a little button on the hinge and lift the leg up. It's a bit tricky and to be honest there's not that many "clicks" (two positions I think) in the ratchet but as the legs are very stiff you don't need to worry about that.
The lowest segements of the legs are around 12mm Ø and if I were a serious professional I would be worried about stability at full extension.
You can unscrew one of the legs and convert it and the centre column into a monopod; but that is really flimsy and my recommendation there would be to use it only as a back-up.
As I said, I'm really happy with the tripod but then my previous one was a 1980's SLIK which cost me about £15.00 back then.
Hope this helps?
