Is there actual geo-differentiation in your widgets or their supply sources? Are you dealing in actual brick and mortar outlets, and how distinct are these outlets apart from location?
Or, are you wanting to do this simply to take advantage of the extra keyword space that the extra "placename widget" vocabulary provides?
Google favors actual local presence, except for a limited number of 800-lb gorilla national directories, so expanding the number of targeted pages simply to pick up more search targets can often turn out to be counterproductive.
