Wow, that is a pretty FW and table. Nothing to feel guilty about.
miriam, my 301 still groans occasionally. My son thought he found a metal to metal spot and oiled it. When it happened again, I took off the bottom, turned her totally upside down and found another grease tube, so I took care of that. I really don't where else to look. I'm ready for a 400 series for piecing and save AR for FMQ if the 15 bobbin doesn't FMQ as well as the vertical one. I like the 400? I sew on at quilt guild. I don't know which one it is.
