I had bullhorns on one of my commuters for several years. I liked them a lot but eventually switched back to drop bars, mainly because bullhorns make it harder to tuck in on windy days.

My bullhorns were simply some old drop bars that I "flopped and chopped." For brakes, I used Nashbar bar ends that I bought for about $20, and I used down tube shifters.

I say give it a try. For some reason, bullhorns made my bike more fun to ride and I kind of miss them -- except on windy days.
