Kodachrome was great film. Beautiful colour resolution, fine grain. Best reds of any film ever made.
I have a digital camera, but it doesn't even come CLOSE to the quality of the old celluloid through Nikon glass.
You can still get it, I use it in my old Nikon FTN all the time.......Kodak has renamed it "Kodachrome Professional", and it requires refrigeration for long term storage, but there is really no substitute. As the OP states, the problem is, unless you have your own lab, processing is a bitch........
I recently challenged a professional photographer to shoot the exact same scene....him with his $5000 Nikon Digital, and me with my 1970 model FTN with Kodachrome (both with the same lens).....process both frames and enlarge both to 16 x 20, and compare the two prints.......suffice it to say that he is a believer now........for big enlargements, excellent color rendition, and fine detail, there is no substitute for film.......
