Where can I find a cheap wireless headset for PS3?

Being a PS3 owner myself, I understand the need for a nice wireless headset. When I was looking to purchase mine, I researched a few different products online and finally decided to purchase one sold by  Game Stop. Brand new this is a $39.99 headset, but if you can find a used one in store, it is only $19.99 and Game Stop's used items are in great shape.

I picked this headset because it was small, noise reducting, could be used in either ear, and could be used even when charging. I often forget to charge my wireless products, so being able to be used while it is charging is a huge plus for me. After using this headset for a while, I was very pleased with how comfortable it is. Some headsets cause my ear to hurt, but I have not had that problem with this one. Some reviews say this headset is very flimsy and staticy, but I have not experienced any of these problems.
