Our museum (a small natural history museum) is working on a grant to develop an audio guide tour of our permanent exhibit. I am looking for sources, prices and recommendations for the audio guides from anyone who has experience with them: what type is best, sources to purchase them, etc. Please email me directly (unless people on the list are interested in this info as well). I will be happy to share the information. Thanks for your help.
