Working models suitable for mathematics exhibitions can be purchased online, for around ten to fifty dollars depending upon the quality and complexity of the model. Simply use a search engine such as Yahoo! Or Google to find a website selling these products - there should be three or four good value stores displayed on the first page on search results. Alternatively, you could look in high street gadget shops. Often these shops sell interesting models that would be suitable for a mathematics exhibition.
