Good oboes are usually made out of grenadilla wood from the Mpingo tree. Some are also made of plastic, however these don't tend to have as nice a sound. Other members of the double-reed family include the english horn, oboe d'amore, bassoon, contrabassoon, and bagpipes. Many oboe players make their own reeds. It takes many tries and quite a bit of patience to make a good one.
Cheaper reeds are typically available in music supply shops, which are a lower quality fibercane.
However, the best quality reeds are handmade. Not many people seem to play the oboe, although it is often a soloist in classical songs and many pieces have arrangements for it. Some people confuse the oboe with the clarinet because of their somewhat similar appearance, but there seem to be plenty of clarinet players. There are a ton of websites that are just about the oboe, as you can see.
