I haven't used the setup you mention, but all of the other Esco products we have are built very well. The buckets are all bullet proof compared to most. We do have an Esco thumb that is strong but poorly designed for the machine. We also used to have an ES80 Esco hammer, that wore out 3 excavators before it was worn beyond repair.
We also have a couple SEC buckets, that are designed to be yard art, as they are made from recylced beer cans or something, absolutely the weakest grade of steel I have ever seen.
