I am going to be pretty blunt here and just say go get that Crescendo RUN don't walk. You can't do better than a Babylock for quality. I looked at the video and that 11.5 harp is just to die for. I have a Brother Quattro (same as the Babylock). I was going to keep it for Embroidery only BUT I LOVE sewing and quilting on it.
That machine has everything you want. Like the song says it will make you "So Dam Happy"! You may not realize it now but sewing and quilting goes a very long way in keeping your brain healthy and sharp. You almost can't put a price tag on that. I wouldn't be saying what I did if you didn't have the money saved for it.
Just go for it girl. I had the money saved for a $7500 one nearly 4 years ago. I got it and never gave it a second thought. Be sure and post what you decide.
