What did you actually use for monster sources?

[Masquerade]

I run a pretty PC-race-centric game, so there are more monsters in the MM1 than I'll ever use. I've probably grabbed one or two from some other source, but not enough to remember doing it.

Same here. 80% of the "monsters" I've used in 3.X have been race-class-and-level NPCs, with the remainder being either MM1 or homebrew.

All of the above, but the vast majority came from the MM or the SRD (often tinkered with a bit, whether it was adding class levels, equipment, HD advancement or changing some ability or another).
