I have to agree with Patrice and Sandpat.
I buy a product not because of name or who endorses it, but if I can afford it, if I need it, and if it is what I want.
Marie does sew and loves it. She may well just be the one to bring in younger sewers/quilters. If not she will be dropped and there are 200 more waiting for the spot.
Marie has been the spokesperson now for about, hmm, three years I think. I bought my Janome because of reviews from folks like you and me and because I actually used one and loved it.
