I would keep the price as it is, as I guess it's about right, sell a single version, but give the user the chance to switch off any modules they don't want/need/use, that way they could customise Poser and stop it hogging resources for features they don't often use, but can still access them when/if they need them.

Failing that, do as they do with Vue, sell a core version for a reasonable price, and allow the user to add modules as they need them.

I've used Poser for 10 years, but have only ever used the Face and Cloth Rooms when I was asked to write a magazine tutorial about each.  I used the Hair Room a couple of times.
