Thank you, Clare, for contacting us! And for the explanation! That's the best cause of a web site crash there could be!
For me the sewedge one sounds very useful and at $25.00 I don't think is too expensive and so what if its plastic? Most of today's sewing machines are too! Would it be better if it were metal? Many of our plastic rulers are costing way more than that! Maybe its just a matter of what value it would be to you.
