I have to admit I've always wanted a life size Boba Fett or Strom Trooper; I'm just not sure I'm willing to put down the money required. Anyways it looks like there is a website dedicated to collecting life size Star Wars characters (of course) and so I thought I'd share it: http://www.lifesizestarwars.com/index.html.
You can look at this persons entire collection of characters or you can view them one by one with pictures and videos. Pretty cool. Note: this is an old website.
