I LOVE my Juki 98TLQ. If all you want is a machine for piecing and free motion quilting, this is perfect. It only sews a straight stitch, but does it so beautifully and you never have to fuss with the tension unless you change the weight of your thread.The longer throat arm makes FMQ easier.
We paid $699. on ebay about 7 years ago. The only thing I wish is that it were lighter when I take it to classes. (I use a roller bag to transport it)
