I know how you feel, a couple of years ago I did the same thing. I went looking for a new machine only wanting to spend about $500 and I came home with a viking saphire 875. It was like I was buying a car to me, but my husband and my mom both told me I needed to buy the nicer machine.
Now we have been looking at long arms for quilting. Talk about being freaked out! Will see what happens.
