We had the same issue with my partner having several thousand slides. I tried a flat bed Scanner (Specifically Epson Perfection 1650) with transparency adapter and the results were not as sharp as we wanted.
If you have a digital camera for which you can get a slide adapter, then this might be ok. But for us our digital camera, Nikon 5700 didn't have an adapter (there was some 3rd party but they appeared to have gone out of business) as an option and most digital cameras now don't. I tried setting this up on my own with a 'jerry rigged' system but was never satisfied with the results. We ended up purchasing a Nikon Super Coolscan 5000. The results are excellent. But, I haven't got it to work under Linux yet (too busy with other projects). If you are interested in experimenting with it, then I am sure that I can sweet talk my other half into lending it to you. Cheers, Ian
