Lostclimate...isn't blenders' sculpting buggy as well? I remember reading of a lot of people having crash problems while sculpting.
And yet even after a google search I still have not run across anyone who whole heartedly endorses Carrara. That and the lack of a trial version makes me skeptical. Most people on the Carrara gallery seem to use it to play dress up with victoria. Though there was some nice original models on the WIP section.
I guess the search goes on for the "complete" 3d modeling app.
