Daz is perfectly justified in pushing Daz Studio. If I remember correctly Daz Studio came out when there was real doubt that Poser would survive.

As a merchant (and I am not one at the moment) you can try lower price and hope for high volume or plan for fewer sales and go with a higher price. I was happy if my products sold 50+ copies in a year. Now I sell models for the higher end applications where I can get 10 sales a year and make more doing it.

If you want inexpensive stuff then look at a membership of Poserworld.
