Hubsan X4 is $36 from Amazon right now

Amazon has the Hubsan X4 for $36 with free shipping right now!  I love having a backup and enjoy watching the price fluctuations over time (I am a day trader..) and this is the lowest I have seen.  It will most likely go back up OR maybe there is a new and improved version about to come out?  Either way it is a win for one of the coolest toys you can own for this amount of money.  Amazon changes their prices all the time, so this might only last a few days.
