After 13 years, I returned to 3.5e D&D relatively late (mid-2005) and I only really began to explore the OGL late this year, spurred on mostly by Paizo's Pathfinder series. I'm an aspiring freelance writer and while I'm looking forward to 4e, I really do love 3.5e, and if the market would support an actual freelance market for it, I would like to support both editions. That said, all of my WoTC monster books are nearly worthless to support 3.5e OGL, so I'm looking to invest (cheaply, I'm being realistic here) in some of the best 3.5e OGL monster books. I already know about Necromancer's Tome of Horrors, Green Ronin's Advanced Bestiary, and Pathfinder's OGL monsters, but what are some of the best books and resources containing open content monsters?
