I realize that it isn't actually very useful to have too many monsters. You don't need more than a handful to make for a good game of D&D. Not to mention that building a new monster for a TSR-era edition of Dungeons & Dragons doesn't actually require very much work, You can put one together in about three minutes if you know what pages to look at.
A good book of monsters is more of a convenience, or a piece of art on the wall of your campaign.
