I like my Elna Supermatic, I have the two tone beige-brown version. Mine was very noisy when I first got it. First round was all about cleaning and oiling, I sort of kept on cleaning and oiling for days. When I replaced the friction wheel it improved a lot (heaps of dust fell down when I lowered the motor). The noise isn't bad at all on slow to medium speed, but it gets louder on top speeds. Mine is very speedy, more so than my modern machines. I went for Finish Line Ceramic Wet lube (it has teflon), I like it, but there's a limit to what teflon can do. I oil every time I use it (which isn't everyday) I pay extra attention to the worm gear behind the Elnagraph, and I unscrew the top lid of the free arm regularly (not every time) to reach all the gears and hinges down there (I don't think I reach them properly from the two holes on top). You have taken the bobbin case appart? As mentioned, it's not very noisy on lower speeds, if it's worth to keep going over oil points everywhere, but for tops speeds it's louder. It's not unreasonably loud when I compare it to other machines, but it has a different sound. I quickly got used to it. I only use top speeds for some zigzagging jobs and a few of the cams. Another favorite of my is a Singer 201, it's in a table and the flat bed makes it very nice for some types of sewing.
