The bars I like are a cheap set of Wald chrome steel. the LBS has them for about $10. You can see them here. They have a slight rise and the grip area is canted slightly to the rear. On my bike, I adjusted the "rise" more forward than up. They're fairly narrow as-is, and the grip area is relatively small, which may make it difficult to mount some kinds of brake levers and have enough room for grips. I have some Tektro/Nashbar bullhorn brake levers that fit nicely on these bars.

I even ran these bars upside down for a bit of fun.
