It's a tough decision. You can't go wrong with Poserstyle, Poserworld, or Traveler's Prop Club. I guess it depends on what you're looking for. Poserstyle has the widest range of available items, from lights to poses to clothes - poses and clothes tend towards Daz figures. Poserworld is mostly clothes - with Posette and Dork still somewhat suppoerted - and models, especially buildings. (Oh, I really love their buildings!) Trav's Prop Club is mostly props (hence the name) but has a wide variety and tends to have theme months. Poserstyle and Poserworld are approximately the same price while Trav's Props Club is much less expensive. You can preview the different sites to decide which one fits your needs best. All three are high quality, so you won't go wrong by choosing one (or more) of them.
