I'm finally digging into some of the older posts (there's too much on these forums!
)...
My quilting teacher said she had her machine swapped out electrically as some people are talking about. She explained how EASY it was for them to do it, and how expensive they charge for it (I don't remember details, but if you need assistance I can ask her when I am next in the shop). So make sure you shop around if that's the option you choose.
I myself left my Brother in the care of my mother. (heh)
But alternately, you can find some sewing machines fairly reasonably priced. I know of a store where I got my now-beloved little Singer Featherweight, the envy of my quilting classmates for only 99 quid. But I've also seen some second-hand ones for very cheap (after I bought the Singer, of course!). For a while, my mom was trying to convince me to let her buy a small battery-operated one (my flat is small and space is important!) that I could use for small repairs -- it depends on what you need it for, really. If you want details on that (from a US supplier), I can find out more from her.
It really depends on whether you are very attached to your machine, or if you think you may be moving back to the States in the future, I guess. Personally, I would leave it behind and find other options here, especially if you're not all that sure you'll need it right away. Oh, I just thought of another option if you're just going to need the machine for a couple of things but you're not really sure, my quilt shop (of course, I mean the one I am most attached to! I don't own or anything wonderful like that.) rents out their workshop, with use of machine for some set hourly rate.
Good luck on your move. Feel free to email me (tricia AT electronjam DOT com) if I have babbled excessively but usefully and you have more questions!
