Clothes and character sets are the main thing for me. I don't know HOW MANY thing's I've bought at Thorneworks but it's a considerable list. I've definitely shopped at Renderosity the most, but DAZ is up there, too. And Poserpros, now that I found it. I find DAZ is good for basic sets (Mike, Victoria amd Mil Kids) and basic clothes; Renderosity is the best for add-ons, hair, environments, props and textures, and Thorneworks has great characters. Kozaburo is the king (or queen) of free stuff. Renderosity has AN AWESOME free stuff selection too!
