I've had the same impression about the lack of a good 3D tool to do this 
(that
is available for reasonable cost).

This is a little off-topic, but the sourceforge update e-mail I just got 
refers to an application
to be used for drawing house plans.  Putting aside for a moment the lack 
of appropriate models
etc., I was impressed by how easy it was to adjust the view (rotation, 
zoom, position ...)
with this tool.  Maybe some part of their UI or rendering code would be 
worth looking at?  It appears to allow you to vary transparency as well.
