I cut my 3d teeth on POV-Ray, and while it truly is an excellent render engine alot of new users are turned off by the fact that you basically code in C to generate the picture. For others that's the total turn on

There is an excellent wire frame modeller that sits on top of POV-Ray called
Moray. It hasn't been maintained, unfortunately, so newer POV-Ray features like "media" aren't supported. And some other infrastructure has fall away (like the
IRTC) - though some inventive types have taken up the torch with
the TC-RTC.
That's why I suggested Blender - it has a built-in wireframe modeller, a bazillion tutorials, and it's own wiki-book. Also in terms of speed, POV-Ray is a renderer in the truest sense. Apps like 3D STudio have the option for scan line rendering which is much much faster (though reflections are not as good) - not sure if Blender has both or not.
