basic trellis and fences for roses

This spring I will plant several climbing roses. I have been looking at options that I might do or hire someone to put up. I am not talking about arches and arbors, just vertical supports of the cheapest, simplest varieties.

I have a workshop with a blank wall. I thought I would use eye-bolts and air plane wire for two climbers there. I will plant one to over-run a tree, and besides that I will have several others. Things I have considered are:
posts connected with heavy chains
lattice connected to strong vertical supports to make a double lattice width.
copper as a medium for a trellis
PVC as a medium as a trellis
posts for shorter climbers

Does anyone have any suggestions that seem as though they would be easy and supportive? The roses will be the real show, not the trellises.
