I have an Epson Stylus Pro 3880. I use Epson Ultra Premium (Luster) photo paper (17"x22"). I'm extremely happy with the quality of print. However, the price is more than I wish to pay as it has a significant impact on the price/cost point of the product I market. Has anyone found a paper product that is comparable in quality but much lower in price that would work well with my printer? I'm in Canada and shop Canada/USA for paper products.
