I like the look and flexiblity of theses modular framing systems
Does anyone know some of the major differences or limitations
from one sysem to the next.

WAs wonder which manufacture has most economical pricing for
all the modual framing systems out there?

I dont know what the big differences are but I have found that http://www.mkprofiles.com/ is fairly well priced you can get a deflection calc and a price sheet from there website if you fill out the form then you get linked to the download.
