I paid $29.95 at Goodwill for a 1954 black with attachments and case - all excellent condition with only minor wear. Second one (1948 black) was a Craig's List posting at $150. She accepted $60 after several calls from prospective buyers hung up uninterested as there were no attachments, manual, or case. I found attachments for less than $15 and a generic soft-sided case for $2.
