I have a Pfaff GrandQuilter 18.8, which I understand is the same workings as the Tin Lizzie 18 and Vilking 18.8. On an Inspira frame. Still working on my own quilts - have done only one quilt for another quilter, a very good friend - she ended up not liking the top she finished and knew I was looking for some 'practice' quilting - she didn't care how the quilting turned out. This quilt is now a joint donation as a raffle quilt for the Juvenile Diabetes Research Foundation - one of our co-workers has a toddler with Type-1 diabetes and she does a lot of work locally to help bring the families together and to raise funds for research.
I hope that one day I'll get enough practice to offer custom quilting - just not enough hours in the day!
