I found a number of user reviews for the Janome 8900 QCP on the patternreview.com website. It won't link the results, but you can re-create them by going to
www.patternreview.com . Select "sewing machines" from the righthand search box, click on the search button, and it will bring you to a search page. Choose Janome brand from the drop-down window, and put 8900 qcp in the "model number" field. It will bring up about a dozen reviews for me. One nice thing about patternreview is that the reviews often indicate what the user paid for the machine. That can give you some bargaining power when you go to buy. it is helpful to pay attention to the posting date too, and how long the reviewer has used the machine.
