Have to agree about the Ektachrome I never really liked the colours like many others in Europe I switched to Fujichrome back in the E4 days because the colours were just so much better for my work.

I really liked Kodachrome 25 but it was just too slow, film speed & process time, also not available in sheet film sizes, and in comparison I always found K64 a dreadful, insipid film.

I do have a slide projector, and I still use it occasionally, but for other reasons switched to C41 for virtually all my personal colour work about 20 years ago. although I kept using E6 for commercial work until about 7-8 years ago, stopping when clients wanted a different format/medium.
