Recycling old tapes
copying & selling by ebay & al.
good quality tapes i would copy on DVD .. ( but you need good hard & software) especially those ones which til now not released as new DVD
and there will be some which never will be released
as you can buy and sell movies on reels ( S8/N8 etc.) til today on ebay ( soft erotic) or special auctioneers for adult stuff you can buy & sell vhs videos.
