Thanks Darcene & Nancy - Perhaps we can all dance in a circle. I haven't ever seen one of these free arm machines in the flesh, in fact I have only ever seen one black one (owned by my quilty friend)
I am consoling myself with the thought that I have actually made a good investment. I think the 240v motors put people off bidding for them, but as I understand it, you can either get replacements, or have one changed to the other, or get a little converter thingy (technical term). LOL
