Would youbuy 12" DC versions from Hot Toys?
 

or Medicom?

For those unfamiliar, these figures are more articulated and much more pricey (as in $150 each) than DCD and Sideshow.

I really like the DCD 12" figures, but a 12" Hot Toys Batman with all those cool accessories and maybe a removable mask would rock.

I would buy a Thom Starman. I saw a medicom custom Sandman on ebay that looked ridiculously awesome(maybe someone else posted a thread here? I don't recall). Most of my other favorite heroes/villains just seem like they would end up looking dumb. I don't know. I'd only get the fully masked characters.

I'm not that into the pricey statues but if it was a very good one of Nightwing I'd probably hate myself later but I'd get that.
