I saw a set on an America a few weeks ago, they looked pretty good. I couldn't find the owner to ask where they came from but I took some pictures as I figured that I could make up a set. I want black rather than chrome anyhow. Be a project after it starts snowing again.
You can find bars anywhere, any kind you want. You just gotta make sure the spacing for the risers is the same and the holes for the wires. Otherwise, you can manipulate the bars however you want.
I have the bars on my 06 Speedmaster, they are from Triumph, I ordered them with the free $500 in extras they offer, Yes they look nice on my all black bike, Black powder coated would look real fine.

Bellcorse has some, as well as Ma's Cycles. I've heard both bend over pretty easily though. In fact, I've even heard that the Triumph guards bend over, too. At the same time, everyone says all three will save delicate fins if you lay her down.
