In my opinion, if you LOVE the Aria, then that is the machine you should get. Price does not make up for the pleasure of looking at the machine you love every day for many years. I know when I bought my Bernina 1230 I felt very guilty for spending so much money on a sewing machine. That was at the time I bought it. Now, 15 years later, I not only don't feel guilty; I'm HAPPY that I got the machine I really wanted. It was worth every penny.
And honestly, at these price points, a difference of 25% more in price (or whatever the difference is) should not be the deciding factor. This machine will be with you for a long, long time. Get the one that sings to you!
Edit: Oh, and this website offers some interesting insight into Babylock, Brother, and the Aria machine you like.
