What adjustable rockers to buy at a reasonable cost?

Never cheap out on rockers, I had a cheap 200.00 set in a 500 stroker well at 60 mph the roller tip pin fell out and the roller fell off you can guess what happened next yes totalled the entire motor including my eddy heads both sides. Lesson learned, the company actually credited me enough to purchase another stroker combo and was very helpful on the issue. After building my 521 I went with Crane golds 1.5 I like them a little noisey so I will be changing to T&D 1.6.
