I don't know what happened with the X-Factor Angel minimate. Whether it was printed in smaller numbers or not, folks really seemed to scramble for it.
I had a mate hooking me up with TRU releases at the time, and he (absolute legend btw) hooked me up with every single one. Even some of the tougher ones to come by like Moonstone and Bullseye. X-Factor Angel was the one damn figure he never managed to find an extra of for me. I lucked out with an obscure online trade a few months later, but I always wandered what happened to make Angel seem so difficult to come by.
