From the same era as my 640-2-11, the 730 has a funky Volkswagen Bus vibe, what with its rounded squareness, WWII nostalgia color scheme of beige and olive drab (despite supposed Swiss neutrality), and its utilitarian, no-nonsense controls. It's a charming design, rather like the unfortunate cousin who actually manages to look pretty if you squint from just the right angle. While it may not look especially large in pictures, it's actually a full-sized machine: tall, slightly narrow in depth but wide. Harp space is generous and the light points directly to the needle area.
Controls for width, length, and an interesting 4-position needle bar control (L, L/C, C, R) are fairly obvious as are feed dog, stitch selection (zig-zag through decorative is 0 - 20 -- Bernina numeration begins with zero) and the right lever enables the following arm across the cam stack. Tension is controlled via dial and small indicator window near the top thread trough. An especially interesting feature is the stitch formation indicator, telling the user at what point in the stitch the machine is sewing. This enables perfectly linking various patterns without guessing, as a new portion of a pattern (such as a new diamond in a diamond pattern) begins when the indicator is perfectly centered on the line in the window. Mechanical and very clever. A built-in buttonhole function means that together with the width lever, a buttonhole of any length can be sewn in one step providing the width lever is switched at the appropriate steps while sewing.
Everything is present except a knee lever and the case. The stair-like storage bin includes a fair number of original Bernina presser feet and original bobbins. (The 730 takes class 15.) The extension bed is inserted and withdrawn easily and without damaging the free arm. The motor is not especially powerful at .84 amp but the inclusion of a speed override to allow for slow, precise sewing is a nice touch. It works flawlessly. Bobbin winding is hidden under its own top right door.
It's easy to see (and feel and hear) why Berninas of this era are so highly valued. This machine runs really beautifully: smooth, quiet, and makes perfect stitches. It's almost as good as a Kenmore.
