Not if the capital cost of what is a very basic implement is taken into account.
I suspect that if we all took into consideration the simple capital cost alone, a lot of kit would not/should not get bought.
However, my purchase was based on other areas, and while the cost was not minor, it has allowed a number of changes in how and what I do with my farming. The intention in the back of my mind was if it was a fail, I can soon sell it on again
