I’ll share my journey. I have a 25 YO Bernina 1090, that feels like it is still going strong. It has a 5.5” throat space. I have quilted up to small queens in the space, but it wasn’t that much fun and took longer with all the fabric wrangling. I thought about upgrading to a Bernina 735 to get a bigger throat space but keep the 5mm feed dogs. When I was looking, the 735 wasn’t yet available in the US, but the Bernina Q20 sit-down caught my eye: 20” throat and takes up less space in my home than a longarm on a frame. That is my current combination: 1090 for piecing and some fancy stitches and appliqué and Q20 for FMQ.
