Well what can I say? These guys make the one's I saw on TV look like amateurs (and the ones I saw were astonishing in terms of complexity for home builds). It really is incredible what people are capable of. I congratulate their innovation and determination to get things this real, it certainly looks very authentic to my non-pro eye. I still wonder a little just how healthy taking a 'hobby' to this kind of level might be, but then why not? Good luck to them.
