IMHO I think we are comparing apples to oranges as it relates to a Hot Toy figure and a maquette. Two different products, with price ranges aimed at different audiences.
In my opinion, if you want to purchase the HT WM and pat yourself on the back for all the cash you saved. Great...more power to you. At the end of the day if you think the purchase enhances your collection go for it. Personally I do not believe the 12 inch HT figure has the "omph" or presence of a 20 inch 15lb maquette. For the perceived increased quality of the maquette I'm willing to pay extra for it. I'm fortunate to have the resources to purchase it, and quite frankly, purchasing the HT version and saving some cash isn't worth it to me.
That's just how i feel as well.
