Anyone know where i can find the collectors edition for a decent price? I've look on ebay($60-80) & amazon has the best price ~ $55(including shipping). However amazon is the 360 version, i can always sell as i already own the GOTY edition(the game). Ebgames has it for $30 but it is out of stock (atleast within a 100 km radius). I really want that bobblehead & lunchbox.

The CE was only shipped at initial launch back in 2008. Either you are going to have to find new old stock in a store, or buy it on the secondary market. Those prices your quoting are what the CE sold for back in the day anyway, so it's not like it appreciated in price.
