Poser isn't  the only program from the Metacreation days, look at Daz Cararra and Corel Painter--both started out their lives being bought and sold.  The current version of Painter is rock solid; I wouldn't let the fact that Poser has passed through several owners  hands discourage you.

D/S has only ever been owned by Daz and I've had more problems with it than I have ever had with Poser.  Not to mention the fact that I had to download and reinstall all of my plugins every time the product was updated (which was frequently).
