I, too have been on the search for reasonably priced LEGO Batman sets, but they are no longer being sold by LEGO since the licensing contract ended and you can pretty much only get them on Ebay or from other private sellers on the internet hence the outrageous prices. My 4 year old son is obsessed with LEGO Batman because of the video game. Good Luck! I would stock up on LEGO Indiana Jones and Star Wars as those go on Clearance (if they go on clearance), because as soon as those contracts end, whoever gets their hands on those will be jacking up the prices when they are no longer available at the stores. I know the large LEGO Indiana Jones Kingdom of the Crystal Skull set was down to $30 at select Wal-marts, while others had it for $83. I was able to pick up the Bionicle Axalara T9 for $25. For a while, LEGO had the Twilight set for only $50, but recently went back up to $99. I'm kicking myself for not picking one up!
