The Speaking Our Language course is once available for purchase. Sìol Cultural Enterprises in Nova Scotia, Canada has them in Region Free DVD format. They will play on any DVD system. There are a total of 4 Series with 4 DVDs each and a total of 18 lessons per series. I purchased the whole series and the video quality is excelent and the cost was less than we paid for the tapes back in the 1990s. The contact info for Sìol Cultural Enterprises is below.
