I love my Janome 8900QCP. I bought her after researching and testing. I have had her almost a year. I love the space (11" harp), the table that was included, how many layers it can sew through, and the support I received (classes and service). I was able to buy a floor model and the dealer even threw in extra bobbins, the double cone stand, and a foot. However, she is not an embroidery machine.
That said, I know Janome has several sewing/embroidery machines that have a large harp. I also looked at those, but embroidery is not my main focus.
You should do your research and go to different dealers and/or quilt shows to try out the different machines to see what you like and what is in your price range. Also, ask if there are any specials going on to get the best price you can. I know there are some specials going on now (getting emails from quilt shops).
