John, you had repair shops robbing you on the repair. I have found the opposite to be true.
They are a parts whore for sure. The parts are not expensive at all. I found that when I bent my eagle they wanted to charge me as much to buy a new one.
The rotary union in the landa water jet is what makes them clean faster and more efficient than others.
I virtually never throw one away and had the original one I bought for years until one of my guys ran it over with the dually.
The body only cost about 27 bucks and the handles about thirty for both pieces. Price the parts for the eagle I guarantee they are higher other than the rotary union.
They are triple in price but you will never need another unless they get stolen or ran over.
