They don't have to be rippled to be ULWD. I bought a 5500watt Camco incoloy element from Home Depot for ~ $17, and it was ULWD and looked just like the one in P-Js Lowes link. It was a bit confusing though, since the Home Depot price label tag on the peg that the element was hanging on said it was Low Watt density, but the back of the packaging says Ultra Low Watt Density. Either way I've boiled about 35 batches with it and it works great. I just did a 90 minute hard boil with an American Lite lager and the beer came out absolutely clean - no issue with scorching for me at all.
If you have a Home Depot nearby, check out the elements there. They seemed to have a better element selection than the Lowes near me.
