Woo Hoo! I LOVE mine, oil it every day I use it and have not touched the tension dial since I bought it mid January. To me, this machine is all MAN... I started calling him Jake but now we've settled on Mr. Juki (he deserves the extra respect!).
I am getting back to daily FMQ practice sessions but to be honest I love walking foot quilting on this machine so much (it has such a gorgeous straight stitch!) that I'm not feeling such a need to learn FMQ as I used to. I'll get there...
