Probably not too expensive. I've had a few Avenir products over the years and found them to make good quality, but affordable accessories. I have some Avenir bar-ends on my mountain bike which have a triangular cross section that I really like, but sadly no longer made.
The details of your stem look a bit different from the one on Sheldon's site. Might just be a similar design.
