Weight: The machine weighs only 18 lbs but the all metal case weighs 10lbs making the combination feel heavier than one would think.
Speed Control: The knee control isn't hard to get used to but I think I would miss the fine control of the foot pedal.
Presser foot: The presser foot uses the short shank but there is NO WAY TO ADJUST THE PRESSURE! Now, anyone using it for any fabrics I think would never miss it, however, for leather you often need to wind up the tension because the leather grips the needle on the way out and can lift the foot.
Bobbin load: The bobbin is standard but the access is not; you have to learn the tricks of finger placement and what things look like when it's correct. Without a great deal of inspection and contemplation you would never see the details of how the thread comes out of the tension spring, but once correct it is there for good. Just like the Lotus the bobbin thread tension is made to be adjusted instead of the "Oh my, what have I done" method used on all other machines.
Sewing: Having a rub wheel instead of a pulley I expected that the start up would be terrible, but no, it is quite good, even thru leather. The hand wheel however takes getting used to. It is a noisy machine, this may be (like the 301) a function partly of being made of aluminum?
It's an easy machine to thread the upper and the thread tension are easy to use. I can see why the following is so strong it is a nice clean machine. I don't have the discs but I don't care for anything but straight, ZZ, and left & right of center, these are what I need and use.
For my automotive reference nothing could come closer than the irreverent SAAB 96; different in every way loved by its fans, laughed at by the uninformed. I of course had two of these little gems in my younger days. It is Swedish not Swiss and 70's not 50's illustrating again how Elna was ahead of its time. The 96 really is crazy and that's why we love it. It was a North / South front engine, front wheel drive, had those large diameter wheels, a V4 Ford tractor engine, had lots of interior space, and was Spartan, just to name a few. Revered for its toughness it was the go to choice for Moto-Cross in Europe back in its day.
