I also like to use buildings and playsets from past toy lines. During the 80's and early 90's almost every toy line released had a playset to go with it. Ebay is good for tracking them down but don't ever overlooked Goodwill or Salvation Army stores. I've found some stuff there before.

Some playsets I recommend (by no means a complete list):
Any G.I. Joe Playset
Ghostbusters Firehouse
Spawn Alley Playset
Spider-Man Alley
Spider-Man Daily Bugle Playset
X-Men Danger Room
MOTU Castle Grayskull (original and revamp)
MOTU Snake Mountain
MOTU Fright Zone
Ninja Turtles Sewer Playset (original and the revamp)
Batcave
Wayne Manor Playset
Van Helsing Castle Dracula
Pirates of the Caribbean Isla Cruces Playset
Police Academy Precinct
Secret Wars Tower of Doom
Roboforce Fortress of Steele
Gargoyles Castle
Swamp Thing Transducer
Swamp Thing Swamp Trap
McFarlane Monster Playsets
Narnia Prince Caspian Castle Playset

Here are some pics using the Ghostbusters Firehouse, Spawn Alley, Spider-Man Alley and Police Academy Precinct.
