A few years ago, I talked myself into purchasing a HV Sapphire for Quilting. Especially for FMQ. If I used the computer setting for FMQ, I had all kinds of problems! mostly tension, some setting issue with having the feed dogs down. When I tried FMQ with the feed dogs engaged, not as many problems. When I was moving/downsizing, I chose to sell that machine and have been doing all my sewing on my Kenmore. It is semi-computerized and is a workhorse. I don't get as much FMQ done, but it is a super machine to use for Quilt as you go! Much smaller throat size, but it will do everything I need it to do! I am not scared of the computer programming, I just like having better control!
