What makes these things hard to get is that's there's only like 4 places in the whole country you get them from. There's newegg, amazon, mwave, buy.com, and i dont know which other stores sell 'em.
Not much competition so they can jack the price up.
You are right that there are indeed not much retailer selling those now.
I know Zipzoomfly 'will' carry them as well...and my local Fry's say they 'Should' have them 'soon'...
and if you are a 'dare devil'..you can try your luck on ebay.
