The Wyncote Toys R Us has the 12" Star Trek figures by Playmates. This line includes Kirk, Spock, Old Spock, and McCoy at $30. These figures seem to be modeled on the new Star Trek cast from the upcoming movie except for Old Spock who resembles Leonard Nimoy. If I found the McCoy for much less - say $10, I might get that one. The others don't interest me.
If Playmates should create a diorama for these 12" figures ... now that would be fun. Probably expensive, but still fun.
