I LOVE my Ashford Traveller. I have a wonderful and lovely Lendrum Saxony which is DD, but I still find myself going to the scotch tension, double treadle Traveller for nearly everything. As you say, it fits into the living room neatly, whereas the Lendrum, with its three legs, trips me up every time I squeeze past. I am perfectly content with the Scotch tension, although as Sally points out, it does have to be retensioned a few times through the filling of each bobbin.
I'm so pleased the others came up with the Ashford website link for you, as I was wondering how on earth to explain it to you without pics!
