Interesting points and I can see where you are coming from when you are saying he is doing it for the fans, but his prices are to expensive to fully convince me in this argument.
If he was just doing it for the fans his prices would be and should be lower.
He obviously gets some of his source prints (not including the english audio of course), from foreign DVD releases from say Germany for example.
If you were the company in Germany would you be happy with this?
There are plenty of titles available with english audio now so I say to people buy these first, and I know what you are going to say I have all titles, so thats why I am buying the franco cleef ones.
There are sevaral options open to you:
Be patient for official releases (who would have thought going back a few years there would ever become english audio versions of some of the titles Wild East has released).
Pester studios, companies that issue spaghetti westerns with e mails on what you want, and eventually someone perhaps may listen.
Bring it to the continued attension to forums like this one.
Search E Bay and other places for secondhand original copies of the Japanese Dvd's with English Auidio. (I have managed to pick up many original titles for under 10 U.K pounds.)
And if all this is a bit to much then why not get another interest, hobby or whatever you want call it and broaden your horizon on a planet which we are not on for very long, now that can't be to bad can it?
