Depends on a large number of factors. Here are a couple - 1. If you own and operate them, do you have the capital to grow as fast as you would like? 2. Do you need to franchise, or will a standard license or dealer arrangement suffice? 3. How much control do you need to exercise over the operations of the kiosk, i.e. use of the brand name, pricing, quality control, sales activities, training, marketing, etc.

Franchising is a another method of distribution. The real question for you is what is the best method? I always recommend a feasibility study be done to ensure the best method of growth, followed by a strategic plan to do so.
