I have been looking for a long time and I finally found a Bernina 930 on Craigslist - I pick it up Saturday. I'm tickled pink! For those of you who use Craigslist, there is a website that will do the searching for you:
http://www.searchtempest.com/
You can tell Searchtempest what you're looking for and how far from where you live you want it to search. Then you can have the results sent to your SSR reader. (I use Google Reader which also keeps track of blog posts I'm interested in and tells me whenever there's a new blog post.)
I told Searchtempest to tell me every time there was a Craigslist posting with the keyword "Bernina" within 250 miles of my home. Searchtempest will also include eBay listings with your keyword. It's a real time saver!
