That's a very impressive build you did there mate! Well done, is it hard to put together? I heard mixed opinions about that, I am thinking about getting one, but my modelling skills are better on the computer then in real life so... xD But you did a very awesome job!
I would say its build difficulty level is about 1.5 because some of the pieces don't require glue, but there are some delicate pieces that can break easily so it has to handled with care, other than that beside some people saying it is a bit too expensive I got it for $55 on culttvman.com, but its well worth the price because its over 18 inches tall, but I do wish it was stable without the base plate.
Yeah it is quite big, 18 inches is quite tall for a kit. And 55 dollars sounds fair, considering this is the only model released of the Tripod from the movie, Randy Cooper made a kit a few years ago which went for $450 so that's very expensive xD Thanks for you info though! And as said before, nice build!
