I bought this instead of the Piranha, the only thing I changed was buying stainless acorn nuts from McMaster Carr.
No drilling the side of the bucket, I ordered it through the implement dealer near me , total with shipping $425.
Very happy with this, it stays on tight and easy to remove, even with about a 3/4" droop in the center of my bucket.
Some have said the Piranha is not tempered steel , this one is tempered.
Basically the same price, they had very good information and answered any questions I had even through texts.
The biggest thing I liked not drilling through the bucket.
