I did put a cheap scanner on my letter to Santa, circa 6 or 7 years ago, with an eye to converting a boxfull of inherited family slides.
It did work, but I was dissapointed by quality. Everthing I scanned had awful colour casts, though the originals looked fine on a (vintage!) slide viewer. I have never got around to scanning all these slides but if I do, I’d probably explore commercial services options, rather than pay more for a scanner I will never use again...
If you do decide to try a commercial service, I’d suggest you dip a toe in the water first, with just a handful of slides. Just in case they are no better than my Amazon cheapie.
