This guy has a room dedicated to statues of that scale...in addition to the rest of his "normal sized" collection. Check out that Galactus you were asking about being dwarfed in the corner of the room:
Wow! Those are HUGE!!!
I have the Sideshow Great Ultron statue. It's pretty damn big and dwarfs my Bowens, even the big ones like Giant Man. As much as I LOVE Ultron, I almost regret buying it because its a pita to display. That Ultron isn't even half the size of this Doom one!!! I just can't buy statues that are the same size as my 11 1/2 year old!!!
One thing I keep forgetting is that I don't have a comic collection or collect anything else really, so as big as these things are, I can find the space.
That being said, 1/2 scale is too much for me, both in terms of price and space. 1/4 scale (like your Ultron) is about perfect for me, because you get the detail and presence for a lot less real estate and a lot less dough.
COI, how do you display your Sideshows? Detolfs seem wasteful, as you have to take the middle shelf out to accommodate the size. Do you use shelves? Or a different display case? One of the reasons I haven't dipped my toes into the Sideshow pool yet is because space in my neck of the woods is expensive. I'm trying to find a nice display case that can fit larger statues without getting something custom made.
I think detolfs are for small statues but I also wonder which good to display a statue from sideshows.
