the 66 an 99 are not featherweights. They are what has been called 3/4 size machines. I have two 99's and they sew wonderfully, but are certainly not a featherweight. My original 99 I bought in Waco TX for $25.00 in 1972. I bought my second 99 off of ebay for $29.00 plus shipping last year. Both are great.
