Cleaning mounted slides (pre-scanning)

[slintz]

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 don’t 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!
