123D Make Now for MAC and PC! ! Allways free! 
Thanks Pilou, already playing with Moi!
Latest builds of blender here
Official new “skin modifier” included now. Much better than Zspheres if I may say so, as it also joins vertices and does topological holes.
Topology is impressively clean and compatible. So, an ideal assistant for sculptris base meshes.
I thought you died !!! good to hear from You !!
A second thought,
This " I thought you died !!!" is killing me LOL
What may dies is this forum, I keep admiring excellent works of sculptris, posted in blenderartists.org community but not here.
Yeah, this forum is dying. I wonder why.
Boo. I don’t want this forum to die. I just got here. I read somewhere that a new version of Sculptris is in development. Is this true?? Anything that would make an already amazing program even better would be great! I bet that would liven up the forums, too.

TopMod 3D is a freely available topological mesh modeler.
TopMod 3D is based on a new paradigm that allows dynamically changing the topology of 2-manifold polygonal meshes. The new paradigm always guarantees topological consistency of polygonal meshes.<span style="color: rgb(255, 255, 255); font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px; line-height: 18px; background-color: rgb(20, 20, 20); ">

Yes, 3DRad is Good fun! for those wanting to try … here’s some tips…
Get Lithunwrap from www.ShareCG.com … you can convert the standard cars and roads from DirectX (.x) to .obj to import to Wings3d or Blender for Scaling.
Get Wings3d … exports straight to DirectX … Triangulate your mesh.
Even Sculptris models can be imported … Normal Maps too … but try keeping it Low-Poly (10K or less)
3DRad is DirectX based … you can animate in Fragmotion or CharacterFX … or try your luck with Blender.
Easy to Create/modify, import/export (IGES, STEP, BREP), repair/clean CAD models
Supports interoperability between CAD modeling and computation software (CAD-CAE link).
Mesh CAD models, edit mesh, check mesh quality, import/export mesh (MED, UNV, DAT, STL)
Makes easier the integration of new components into heterogeneous systems for numerical computation.
Easy to Handle physical properties and quantities attached to geometrical items
Display computation results (scalar, vectorial)
Provides a generic user-friendly and efficient user interface, which helps to reduce the costs and delays of carrying out the studies.
Reduces training time to the specific time for learning the software solution based on this platform
Manage studies (create, save, reload)
Provides access to all functionalities via the integrated Python console.
