I use this kind of set up.

I build my shaders using my MATHelper tool, which makes it easy to construct a variety of standard shader structures.

It also has the facility to rename nodes, copy shaders from one material zone to a selection of others (optionally retaining the existing texture maps) and drag and drop replacement of texture maps. It's quite handy.

And free :-)
