nectaris; if you buy these, you still need to acquire the receiver for them. I enjoy using mine. The battery life is pretty good too!
I'd say to expect to pay between $80 and $110. These prices are for "new" condition ones too! DreamStars has a new one right now for only $84 ( which I think is a great price!). I bought a new one from them a while ago for $110! Ya, I feel like a tool now that they lowered the price Mad
