I like my syntace streamliner bars, they were fairly cheap, and really really simple, clip them on and you're pretty much done, nothing to adjust or fiddle with other then pad witdh which you have to remove the pads for. I also like the straigh bar design which puts my hands closer together.

I also liked the profile design aerolite bars, simple, quick, but they feature adjustable reach, which is nice if you're don't fit into the medium or large bars and need something you can fine tune.
