I have Poser from its beginning and now i use sometime Poser 12...and for now i don't plan to buy version 13 .I still have many Poser stuff  ...but i use not too much and i open them directley  iinside DAZStudio.I also  use DAZStudio  from its beginning  (DAZStudio pro wasn:t then free).. and now i use it most of time  because it have lots of stuff and the characters are very better than the one coming for Poser. DAZStudio is now free and,according to me , more easy to use  and the new stuff are constant and have an increasing quality.
