Are you moving here permanently? I would definitely buy a machine here. Our voltage is 240V and the plug tops will be different.
I have always had Janomes and always liked them. I now have the 7700 and love it but if you don't want to spend that amount of money there are lots to choose from that are less expensive. The 7700 does have the bigger harp though. Whatever you decide on, I would definitely suggest you get a machine through a dealer rather than the chain stores, so that you have a good backup service if needed. Besides, I do believe they may be a different line of machine to those sold through the chain stores, although I can't say for sure.
I can't help you with what quilt shops are available as I'm nowhere near either Portlands here. But if you google I'm sure you'll find some information. Try
www.yellowpages.com.au and look up craft or fabric stores in the Portland area and see what comes up.
Good luck with your move and I do hope you like it here
