Nuc,
I've found Wings3d to be the easiest 3d program to learn, and you can start getting "results" pretty quick.
Its also free.
Here are some links:
http://www.geocities.com/paulthepuzzles/aardvarks.html lots of tutorials
http://www.geocities.com/paulthepuzzles/aabasics.html very informative about the various functions
http://www.wings3d.com/doghouse.php video house building (runs through very fast though)
http://mbx.streetofeyes.com/index.php?topic=17.msg24207 covers "how to" add an item to "mount and blade" but the info is universal
http://forums.cgsociety.org/showthre...4&page=3&pp=15 covers heaps of different things about w3d.
Blender is huge - very very steep learning curve, but is as close to a commercial program and I believe you can get. Also free

http://blendernewbies.blogspot.com/
http://www.tutorialized.com/tutorials/Blender-3d/1
and just "google" blender for more info than you might want.
I will say that I am still learning Blender but in the mean time I'm working with wings3d.
