I don't have any to sell, but can provide some advice. I have built both kits (Meng and Orochi) and reviewed the Orochi kit; not impressed.
If you really want the Orochi kit, you would be much better off getting the Standard Edition, esp. at this price
. The added gimmics of the Deluxe Edition kit don't really add to the quality of the finished model; it still is inferior to the Meng kit. You can see my build review here
of the Orochi M3A3.
I personally would stick with the Meng M3A3, which does not come with an interior included, but as a separate kit.
The Meng M2A3 comes with the interior in the box.
