How funny! You must have deleted the post I was trying to respond to, because it is gone!
To answer your original question: No, I have not checked Office Max here in Austin, because I figured that with all of the CD-Freaks we have running around in this town, they would have snapped them all up! I guess I really shouldn't assume.
Even though I did find two NEC 3500A's, I wouldn't mind having a Mad Dog, too, especially since bitsetting is available without the necessity of flashing the firmware. There is an Office Max right around the corner from my house, so I guess I really should go up there and rummage around to see what they have.
