Would you consider using small HO queenposts and living with them being a little oversized? Grandt Line makes them (if you can find old stock around), and then use fine wire or fishing line for the actual rods? PD Marsh makes some in white metal too.
They would be round and 3-dimensional, which I always liked better than flat etched ones, even if they are a little big. If you use the smallest HO ones, I think they look good.
