If you become a member of patternreview.com, you can look up posted user reviews of specific models to find out more about price paid, pros and cons of each machine, etc. It really helps. Do pay attention to date posted as that often is associated with price paid new. To get approximations of price used, you can do a search on eBay and click on “completed listings only” to find out whether a machine sold and, if so, for what price. Sold prices mean much more than asking prices.
