I just built a headphone stand out of miscellaneous Ikea parts.. lol. It's so solid you could probably kill someone with it. Everything is that stainless steel stuff. It all cost me about $15 to $20 max to build. (some of the stuff I found in the 'returned items and clearance' section)

Main stand portion: BJÄRNUM Bracket 11''
