It really depends on your idea of a reasonable price. List your must have features and then try out different brands that have the features you want. I have owned a variety of machines but my last machine I bought was a Bernina QE 440 with the Bernina Stitch Regulator for FMQ my own quilts. That was a must have for me.
As important as the machine you choose, is a good warranty and good shop/repair people to support you.
