Second to Isisaxon. My question to you is how are you going to have your Kodachrome films in process? You cannot use E-6 processing, because they are different from other transparency films. From my understanding, there are only three labs in the world that process Kodachrome film, United States, United Kingdom and Australia.
Even during my years at RIT (Rochester, New York), I dare not use Kodachrome. It was not because I couldn't find a lab to process them (The Kodak Company world headquarter is just about 5 miles away from the RIT campus), but the processing was very expensive like US$12 a roll. And that was about 5 years ago. I am sure it costs more to have such film processed now.
I don't see the point unless you are willing to pay.
