Hello again Rosalie
I've asked a friend to ask around her sewing club and also been in touch with a Husqvarna dealer here in WA. He says the System Five is way out of date (as you already know) but he does have a 4D Basic Embroidery package which will work with the Viking Orchidea Emb machine for A$400.
If that info is of any use to you please let me know and I will put you in touch with the dealer. A$ at present is 95cents compared with US$, the best it's been for years :!:
