The BUSA DR1 is out of my size range, so it wouldn't be a player for me.
Since GP discontinued their very nice DR1 ARF just about the time I decided I wanted one, and this NM one has fallen off the planet (if it ever existed at all), about the only choices left for the DR1 enthusiast who is 'hauling/building room challenged' are building the VK/Proctor version, or scratch building. I'm kind of on the lookout for a VK kit on the 'Bay while waiting for this one, since we apparently have a long wait ahead here. [
