I would highly, highly, highly recommend going to The Sewing Room in Frisco. They sell Janome sewing machines and have a wide range of sewing machines, esp. some really great and lower-priced entry sewing machines. They are really good about talking to you to find out what you will use it for and what features you want, and will show you what's available in your price range.
They give you a free class to help you learn how to sew your machine, have great warrenties, and the first one-year maintence/clean/repair is free. All the repairs are done there in their store, so you don't have to worry about trying to ship a heavy machine somewhere, or try to find someone who does repairs/adjustments.
My mom bought her sewing machine there, and she just loved it, and I was so impressed with their service that I went there to get my quilting sewing machine. We use our machines almost every day and they have run so smoothly! They also have fun other classes that teach you more skills and techniques and you make fun projects!
Here is their website:

Click on the "Sewing Machine" link on the left, and then click on "Entry Level Machines." My mom has the older non-computerized version of the Sew Precise model, and she just loves it!
Good luck!
