Talk:Instruments used in gastroenterology

I have started to build a list of equipment used in gastroenterology. I will add further (and newer) images when I have a chance to photograph the articles mentioned (at work this week, hopefully). I am unsure how to reference this article; since I use this equipment daily, it has never occurred to me to look them up! Other than linking to commercial websites of the manufacturers of these instruments (which I am loathe to do, since this would essentially be free advertising), I am at a loss. Suggestions would be appreciated. Gilo1969 (talk) 14:33, 3 January 2009 (UTC)
