I got V4 and the morph ++ package from Daz (only paid about $14 for everything). I already removed V4 for a few reasons:

1. It was too new and I wanted to find out a bit more (I can always RE-install it later), so the fact that I am out that money is trivial.

2. I noticed that some Renderosity vendors had V4 skin textures. I noticed later that they are no longer there.

3. I tried adding a V3 texture to the V4-V3 character and it didn't work.  I REALLY don't want to loose all my textures and clothes.  I really, really, really (did I mention I really dont?) want to have to buy all new everything.

Am I disappointed? No, not really, I just need to do a bit more research to understand how the morphs work.  I like V3 here, I can see all the morphs at the body level, without having to select each portion of the body.

Hope this helps
