I picked up a set of bars that are similar, if not the same as the ones you are looking at for $20 a few months ago. They were new and IIRC marked at $30. Decent enough, but the anatomic bend doesn't work for me and I've since replaced them. I can't tell what kind of stem it is from the picture, but if I had to guess I'd say it's in the $10-20 range.

Are you converting a mountain bike? If so I think a set of flat bars or risers with bar ends might work/look better.

Where are you located? Are there any local bike shops in your area where you can check out different types/sizes of bars & stems in person?
