Happy Birthday!!!
Be sure to ask about floor models too. Sometimes you can get a great deal on those. I have a Kenmore 19233 that unfortunately has been discontinued, but it is a great machine.
I have been searching for a new machine, with a larger workspace. One of the key things folks told me to do, was to 1. Shop around, try them all. 2. Take samples with me that would represent the type of sewing I would do. 3. Make sure you like the dealer, because that is where you will get your lessons on your new machine. And if you have an issue you want folks that are friendly and nice to deal with.
