I have the Pfaff PowerQuilter P3. It's a nice machine and the only issues I've had have been user error. I was considering the BL Crown Jewel and the Juki Virtuoso as well, but decided on the Pfaff because of excellent local dealer service. If the dealer hadn't been a consideration I probably would have chosen the Juki because it was a little less expensive. I didn't like the bobbin winder for the Crown Jewel, but the computer system on it seemed very user friendly.
I'm still struggling with my LA although I've had mind for nearly a year now. It doesn't come easily to me and I don't love the process the way I love planning and piecing the tops, but again, it's user issues that I struggle with, not the machine.
