Replacing an Infloor mixing station

I have to replace one of these and I imagine there will be plenty more in my future seeing as they were very popular here back in the 90's and 00's. I could go with a simple circulator and mixing valve, but I am also interested in another "mixing station". I see Caleffi has one (do they sell them without a manifold, hr?). Has anyone had experience and satisfaction with others?

Thanks in advance!
