I love my FW, as do so many others. I bought it because I didn't want to try to take my Bernina to classes and retreats...it's too heavy and too expensive to go lugging it around! I use it only for piecing or small quilting...quilt-as-you-go...projects. It's my backup when the Bernina is in the shop. And it's straight stitch is fantastic.
Ease of maintenance is important to me too....you can learn to maintain it on your own. There are wonderful resources available through the web. And it's very straightforward mechanically.
And, for me, it's sentimental....it makes that old-fashioned sewing machine sound and reminds me of how many women sewed on those little darlings!
