The new Juki that will be coming out (Virtuoso) has the option of a computer. Maybe you could get it for free motion at 7500$ now, then add the computer later when you can afford it?
I have the Pfaff PowerQuilter P3, which is made by Tin Lizzie. I'm very happy, but mostly because of my dealer, who gives me private lessons and answers my many, many questions. I looked at the Crown Jewel. It was less expensive than the HQ Avante in my area. It was a really nice machine and honestly, if that dealer would have offered the same support as the Pfaff dealer, I probably would have chosen it instead.
Good luck! I hope you find the right machine for you.
