IEC cords come in a variety of configurations, it's just a set of standards....and the HQRP model specifies what connectors : Connectors: IEC C17 Type to NEMA 1-15P so if you search for such you should get some more choices to choose from but the HQRP looks viable, altho I didn't notice a UL certification which would be nice....
ps I wouldn't worry about the 18 gauge wire for that amp/length.....
