Hello,I found your site through ec21.com. I am inquiring about the Digital Cable TV Converter ( Model : Digital Cable TV Converter, Brand: Digital Cable TV Converter ). I am starting a business selling electronics where I live in Chicago, IL. And am contacting several manufacturers to find the best products at the best prices. I would like to know Price per a unit? What is the minimum order? Do you have a branch or showroom in the U.S? If not, can a sample be requested? Also, pleaselet me know if the price per unit includes royalties on applicable patents to this product. And finally please inform me of any trade shows your company attends in the United States.Truly, Gila Sery
