Best place to go is Poserworld for sure. I do have M1/V1, M3rr/V3rr and Steph1. All of the stuff I do use in my scenes for these characters comes from either the DAZ PC Club or Poserworld. Here's what I would recommend, get a DAZ PC Club subscription and buy as much stuff as you can for the old figures (and perhaps new figures) and the quit the membership. Get an annual subscription at Poserworld and renew it once a year. I did this too. Well, I'm still a member a the DAZ PC Club until they release Bryce 5.5, but after that I'm quiting my membership. Why? Because there's no new stuff coming for the older figures at DAZ anymore and most of the stuff they do release isn't of my interest at all. After all how many clothes can one use? I've got more then enough clothes by now to create 100's of scenes. I don't have a annual membership anymore at Poserworld, but upgraded to a lifetime one. Why? Because I'm very happy with the price and the number of various items that are released every week. The quality is good and the variation too. Also the price you pay at Poserworld is excellent. As for Poserworld not being enough, perhaps not, but that depends on your needs, they've got lot's and lot's of stuff there. Then again how much will you use after all. I know quite a number of people here and at DAZ buying and buying and buying some more clothes and other items, and ending up never using the stuff at all.

Artwork and 3DToons items, create the perfect place for you toon and other figures!
