Goodwill must be the place these days for 306es. A couple of weeks ago, I found a "K" in black and gold, also for $25. It was in excellent condition, mounted (incorrectly) in a Queen Anne mahogany cabinet, with bench. Just the ZZ cam was in place; no accessories with it. I cleaned it up with some non-abrasive hand cleaner (GoJo), waxed, oiled and put in a new needle and made the "Baby Blocks" quilt that I posted here this morning.

Only the free-motion work was done on another machine.
The machine had a standard needle installed when I bought it and it stitched fine. I replaced it with the correct 206x13 needle for this model and it continued to make perfect stitches. I have many 206, 306 and 319 machines (too many) and I've never been able to sort out the controversy with the needles.
