I don't use fancy stitches all that much and buttonholer even less often. I have several nice vintage machines which all work fine, but, I still like my Walmart/Costco version Brother machines for piecing. For FMQ I have a Brother PQ1500 which I really like. I've been dithering over a sit down mid arm, like a Q'nique but it doesn't come in a table anymore. Tried the handiquilter but I don't like the orientation. Same with the Juki sit down. Brother makes a sit down that can go either way, and looks exactly like the Q'nique, but, I really do like the PQ1500. I guess one day the answer will be made clear to me!!
