unfortunately they’re very difficult to find online. 😦 I think amazon video is basically the only way to get them streaming, and netflix might possibly have the dvds (if anyone still actually uses their mailing service?). I’d say the show is definitely worth giving amazon money for, though.
(we are renting the actual physical DVDs from a real brick-and-mortar store, it’s all very quaint. however, most places that are not seattle are not likely to have a video rental place dedicated to old and obscure shows/films)
