Shop around, go online, find the best price for the model you like.....after you have tried it out in the store. Remember is you purchase from a reputable online dealer, there is no sales tax and usually no shipping. That is if you do not need classes.
If you need instruction, then find the best price on line (Call the dealer directly), then go to your local shop and see if they will match the price without tax. I have done this numerous times.
Know the features you cannot live without,....such as auto thread cutter, numerous decorative stitches, quilting amenities etc. Take a quilt sandwich with you. Best wishes in your quest.
