Well, in this case, I don't have a model in contention, so no worries.

And in past cases, I've never felt guilty for voting for myself. If I felt my model wasn't good enough to earn one of how ever many votes I had in that case, I just didn't vote for it (that's what I did last time, anyway), but if I did think it was good enough, why feel guilty for saying so with a vote? If it was a rule, I'd have no issue with it, but lacking such a rule I don't see a problem voting for whatever entries make my cut, no matter WHO was responsible for them.
