I got my Beyer T 5 p new for $899 on buysonic, and I would have gotten the Fostex TH-900 for $1010 on headphones.com, using their "20% off if you sign up for our newsletter" coupon. Not sure what the Alpha Dogs, listed at $999, discount to, but these were both heavily discounted, new, from their list price.
the alpha dog prime is $999, i'm talking of the first alpha, and i'd probably get one used if i went that way
