I bought some about a year ago from aamericanflooring.com. The ones that I got were 3/8" brushed nickel and were $19 each at that time. I later found that I could have bought them at the local tile shop, but I don't know what their price was. When I looked, I didn't see much offered at HD (just aluminum and oil rubbed bronze, I beileve). I think they also had some nickle, but it wasn't the right size/shape. I don't think our local Lowes carries it.
