Seriously. I've been checking the used page almost religiously, and I've never seen one pop up. Bluh. Here's to hoping there's a deal on it soon, somewhere.
If u have picked it up at TRU for $45 (or $30 thru the glitch) then I recommend waiting for BF or if u must then its $50 at TRU now (think of $5 + tax for NukeTown)
