I recently havev been given the oportunity to purchase an older tornado that is still in the original packaging. I can get it for $800, all I have to do is put it together, despite thevious flaw in this plan that I will likely have to buy lots of little things to do this. How difficult is it really to get this thing put together CORRECTLY. Is it worth it?? I'm pretty good with my hands, but I am no craftsman.
