Best place to get a few of the BBBlacks?

I don’t know if my kids were playing in my office, but yesterday I had a working BBB prototype that I was trying to port The Deck, my custom penetration testing and forensics Linux distro, on. Tonight when I got home the thing is dead, no LEDs, nothing. So I was going to buy a few new devices for my pentesting army anyway, but now I’m a little bit more motivated to do it now (also bummed since I was hoping to show this off at THOTCON on Friday). Any suggestions on best place to get 5-10 of these in a reasonable amount of time?
