I think the dimensions are standardized. The differences will probably be along the lines of profile options, hardware options, custom machining options, fit and finish, etc.
i created this table in Sketchup a few years back, its based on some well known designs aswell as my personal preferences.
Unfortunately i never got around to building it but maybe one of you guys might have a use for this ;-)
shoot me a PN for the Sketchup file if you're interested.
