TBone.. I am pro foundation-less... not so much because I want the bees all natural, but because I hate paying for foundation when I have found no overpowering need to use it. If I get foundation as you have, buying equipment etc, I have no argument with using it.
My greatest lure toward foundation-less is ease. Easier to make the frames. Easier to repair bad spots. Easier to rotate the wax out of the frames, and most importantly easier to cut out queen cells or do cell punch to make queens. Draw backs are, More care when handling fresh foundation and more care is required when extracting.
I think Jen's analogy is pretty close, but consider it a bit more like living in a double wide or a custom stick built house.
Personally.. I would get along just fine in a 1960 10 x 50 trailer house, its the wife that wants the fancy living arrangements.. and since the bees ARE female.......
A better analogy would be that the frames are furniture.. You use what you have until you can get something better. We all want a big cushy Lazy Boy, but sometimes we have to make do with a fold up lawn chair.
Your methods and desires are what determine what type of frame/foundation is a lazy boy or a fold up lawn chair.
