I am still using my old Singer Ultralock from the 80's too. It's been totally reliable and pretty much problem free. I have two other sergers that are more sophisticated, but the simple Singer makes a better looking overlock seam. Hubby bought mine for me way back when, as a gift. It was a very extravagant gift for us at that time with our young family, but I have to say I've more than gotten the investment back out of it! Thanks for sharing the video.
