I bought the purple Jefford's version for about half of retail and I'm okay with it for that price. I don't have enough photos of that 1:1 to judge the model's accuracy but its shape is pleasing to me as is the color.

As far as the worth of the box, the reason I like undamaged boxes is because I think I can get more money for the model if ever decide to sell it. If I intend to keep the model I'll take some box damage for a discount unless the box art is fantastic.
