I think its just fantastic that you are quilting. I know what its like for you to sew with just your hands for control. My Husband has had a stroke and he has learned to quilt with one hand . My suggestions is to get a machine that has the start and stop button and one that you can set the speed on. My husband sews on a Viking quilting 11 Machine and also a pfaff machine. they both have the speed , stop and start button. We got the Viking used from a dealer and been very happy with it. Im so happy for you that you found quilting . I find quilting so much fun and helps them long winter days lol .
