Use caution when going through airport security. I recently passed through JFK in New York. I put my backpack camera bag in a tub and sent it through the scanner. When I got to the other side it was still in the tub, but I didn't notice an agent had unzipped it to look inside, and only zipped it half way back up. When I pulled it out of the tub and swung it up on my back everything went flying. Two bodies, two lenses, batteries, filters etc. on the floor. The mount on my go to lens was broken, rest seem to be OK. Fortunately I'm insured. P.S. Don't expect TSA to accept any responsibility.

If you have a few thousand slides, or even just a few hundred, I recommend you consider a dedicated film scanner. I've used a CanoScan FS4000 for many years with excellent results. It scans up to 4000 dpi. I recently moved up to an Epson V550 which has up to date electronics and more features, including dust removal and color restoration. Both scanners produce an electronic file which is convenient for both storage, viewing and sharing. You can create a slide show from your file for viewing, give a copy to your family on a thumb drive, or make prints. Once you've made the investment for the scanner there is little additional cost. By the way, these are dedicated scanners specifically designed for copy work, not cheap run of the mill scanners.
