I only use wsdisplay.com they have been excellent through about 8 orders and never a problem. I even got them to speed up an order that I received two days after placing the order at no additional charge.
Ever tried Orbus? They have a lot of different options at what seems like decent trade only prices.
What do you mean by b2sign being too cheap?Sign Amigo and b2Sign
B2Sign works well for me. Too cheap but great in every aspect.
Phillip at Sign Amigo does the beautiful design.
