MOUNTAIN HARDWEAR BUNKER TENT

has anyone had or got one of these tents ? as i am after buying one but could do with some info about it from people who have actually used or got one, and the only place i can seem to buy one is if i send of to the USA for one, and i would rather try and get one from within the UK if at all possible., even a really good second hand one would do me and would be a hell of a lot cheaper as well , as they retail at about 400 pounds plus, or i supose there is the Rab summit 2 person tent which is also an outstanding tent though Rab call it a bivvi, either one of these i would be very happy with new or second hand, So has anyone got any ideas or thoughts about this ?
