Mavic bullhorns are the bee's knees. Best bullhorns out there in my opinion, for positions and looks (that could be personal opinion though, as some of the hand positions it gives are crazy, and the colour matches everything on my bike) but they are so damn rare that I get to brag about them whenever possible. I got them slightly used off ebay for 32USD. The syntace and cinelli bullhorn bars are comparible in shape, and I'd reccomend those too, although I have not used them personally.
