I say get the one that you can find at the cheapest cost. Yesterday, on Ebay, I was able to find a "loose" Mark II for $145. Didn't hesitate but for a few minutes and bought him. I get him tomorrow too! This will be my first Hot Toy figure and eventually Selina Kyle will be my second, once BBTS ships it to me
Good luck!
That is a very good point.. if you are not picky about original packaging etc.. then you can pick up figures for display, at very competitive prices.
