Anyone know where I can find bars like the ones in this picture:

The model pictured is a 3T Chrono, another model I've seen (in pictures) is the 3T Moscow. I don't care about brand, I just want a bar with extensions that drop a good distance below the stem. I have some Syntace triathalon type bullhorns and they are good, but I want to get lower when I'm on the extensions.

I'd appreciate it if anyone could 1) Recommend some handlebar models and 2) Tell me where I could buy one.
