Best Buy has the Rocketfish Universal Headphone Stand (RF-GUV1203) for $4.79 with free shipping. Features a built-in cable organizer. Good user reviews.
I use a 3M Command Hook. Works great and doesn't take up any space on the desk. Doesn't leave any marks on the wall when you want to take it down either.
Cheaper than a banana hook, I guess. I use a large coat hook on the wall for mine at home.
I have this, works great for me for $5.
