How about I sit in the corner on top of a sewing cabinet?
To be honest, I prefer a straight stitch machine with reverse and a length regulator with numbered increments. The 66 you're seeing in the thrift store has a length screw which makes it more difficult to return to a former length setting, for example. Later models of the 66 do have a numbered lever with reverse. (There are attachments you can add to an older machine to remedy this.) If you need reverse for the type of sewing you do, this one's not going to be able to perform, although many sewers say that reverse isn't necessary and many tailors and dressmakers say that reverse is actually detrimental and should never be used.
