Most of the sessions of Swords & Wizardry Light at various conventions have been with the Mouth of Doom 3d printed dungeon. I learned to appreciate the use of miniatures, which I sorely lack. Pogs are useful but get lost in the 3d terrain. Printable minis would have been awesome and extremely portable, as well as affordable. Normally 9.95, you can snag Inkwell Designs Monster Stand-Ins (Paper Minis) for 1.99. perfect for the frugal DM ;)
Monster Stand-Ins is a PDF of creature miniatures. Print as many as you need! Over 350 images (originally 250+) cover all the most common creatures (orcs, skeletons, goblins, etc.) as well as many uncommon creatures such as a devourer, vegepygmies, and sahuagin. Most of the more common creatures come in several versions--get a kobold as a melee fighter, an archer, a shaman, or a buffed-up leader.The PDF also includes many animals & insects (horses, cats, dogs, lions, bears, bees, bats, rats, etc.) and over different 50 PCs/NPCs.The back of each creature is a silhouette of the front. Each mini is available with or without a label.As much as possible, creatures are grouped on pages of similar creatures to make printing easy. (If you need hobgoblins, you'll likely want goblins.)Each mini has a front and back on the same side of paper and when folded: Small creatures are 1.25" x 1", medium are 1.5"x1", large are 2"x1.5", and huge creatures are 2"x3" and a few are 4"x3".
