Donna,
Perhaps after looking at the big picture, (this forum and my house full of other machines ) I could have said: "What's need got to do with it?".
I don't "need" 5 Singer 66s. Or 4 treadle machines. Or 3 or 4 Japanese ZZ machines with multiple cams and built in stitches. Or a half dozen miscellaneous Singers. But I saw 'em and wanted them and got 'em.
I don't mean to be two faced, but I've been thinking since I answered your PM this morning ( I woke up a bit ) and it really just comes down to wanting the machines and having the ability to pay for them.
I do agree though that the prices are all out of proportion to what your getting.
Joe
