A few years back I was in some photo-lab in Florida and I saw they had an "automatic" slide blower. A small counter top machine with a slot for a mounted slide. Push it in and a fan inside switches on and blows dust and such off the slide. If it works as I remember, this would be an excellent tool for quickly cleaning my slides before popping them into my scanner. One problem my web searching has turned up nothing like what I am looking for. I dont even know what such devices are normally called. Anyone out there know: * What these nifty devices are called? * Who makes them? * Where I can buy one? * What features to look for / avoid? TIA!
