Scott, first, it's not fair to compare an image computed by the photo creation tool at its best quality level and taken from a visitor point of view, to an image computed at the worst quality level and taken from an aerial point of view.
After that, using Google could give you more choice if Hans proposal doesn't fit your need. In that case, don't forget to take care of the copyrights of the images you'll use, according to your goal.
By the way, a less aggressive tone would be welcomed. As you noticed, Sweet Home 3D is free, as well as is the support you get here from volunteers (and even if support wasn't free, a kind tone is always better). Please, don't discourage them.
