I wasn't happy with any of the options for rolling up dungeon monsters. Strictly from desperation, I stocked the first level of my megadungeon with some heavily fudged use of a 3rd edition encounter web gadget, the kind that gives you dragonforged were-undead goblin rangers with the Mighty Cobra Clutch feat.
So over the months, I went ahead and cobbled up one of my own with a more old-school feel, both in source material, and in coming up with too-big-to-fight encounters every now and then. It has my usual table style - roll 2 keep low, d6:d6 rolls - and it manages to stock the lower levels heavily with Varlets & Vermin monsters. Download from the right. Let me know if it doesn't work; once again I've tried the "download from link only" version in the vain hope that Google Docs will actually work.
If you're interested in hacking it, let me know and I can send you a Word copy.
