Ryzomes are only a few bucks each, you'll know what you are getting & typically, you don't need a big (12-16 feet, not 7) trellis until the second year.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
