Almost any modeler will make meshes suitable for Poser.  I think what will be more important is finding which modeler works the way you want to work;  that is, find the modeler which fits your way of thinking and problem solving.

     Unfortunately, you'll just have to try some to find out which one fits you best.

     My comfortable old shoe is Silo - $159 US for the Pro license, good for three computers.  http://nevercenter.com/silo/

     When I need to do weird stuff like a tapering radial array or 3D tunneling (kind of a "nuclear option" for Booleans), I break out modo - $995 US, with a license that permits installation on all of your computers, though you can only have it open on one at any time.  modo is also a full-on rendering studio.   http://www.luxology.com/modo/index.aspx

     I have licenses for Shade LE and Hexagon, but haven't used them much.  Just didn't fit me.  I also have LightWave 10, but haven't even tried modeling in it, so I have no opinion either way on it as yet.

Poser 12, in feet.
