JMiller. I like your advice about "if it ain't broke, don't fix it". I was given one that looks almost brand new and worried if I should take it apart for cleaning etc. It sews wonderfully. I tried out three of the several attachments. Wonderful. Cleaned out dust bunnies around bobbin area and under needle. Anyone with advice feel free to pm me. I want to use it but want it to be ok. Thanks, Teresa
