Someone probably beat me to the Dalek(s) in the case, then, since nothing stood out as being obviously beefy.
That's what happened the first time I found a case of series 1 (at Fan-Expo in Toronto). All of the Daleks were gone, but I didn't know that. So I spent all that time looking for the largest pieces in the bags. I ended up with a few Doctors, an Angel, an a couple of the lizards. After that case sold out, they set out a fresh case. I picked up a bag and...it was a Dalek. There was absolutely no confusing it with any of the others.
Kinda makes you feel a bit foolish when you do finally come across one.
