I think the Comp magnum's may be about the most economical roller tip rocker available.

I had them, but swapped to Harland Sharp rockers after one of the comp's loosened up on me on the highway. I want to be straight forward that I don't know if this was an installer error or a product error. These rockers use a ball and cup trunion with self locking adjusting nuts. I had them on my #62 heads, and transferred them over to my KRE heads which is when I had issues.

Of note, the cups on the rocker arms were blued pretty decently which I felt a bit uneasy about, but may not actually be an issue.

The HS rockers have been great. I set them once and checked them once and they hadn't moved. They sing like a sewing machine a bit, but they've otherwise worked well. They are about double the price of the comp magnums though.
