I don't know where you are but here in the UK, it is showing almost continually and the DVD's individually have been released by amazon.uk, very cheap but oddly here I can no longer access the official site and amazon.com have withdrawn the DVD's. I have taken most of my work here on wikipedia from the more detailed work I did (29 pages)on the wikisite TV IV  where I will add some more images eventually. My favourite 'western' is Queen of Swords a Zorro ripoff made between the two recent Zorro films, only just shown in the UK 7 years after cancellation, and I did 40 pages on TV IV
