These are the reasons why I got white one at GS for 50. Sony M2 cards and charging dock are hard as F*** to find cheap. I had the buy my 16 GB'er for 35 bucks, almost the price I paid for the system. The dock is like 3 used at GS but almost nonexistant or the clearks are too lazy to go check for them, everywhere is over priced (ebay/amazon).
I actually had trouble finding component cables for it when I got it. Had to drive to a TRU 30 miles way from my house for it.
