Headphones like A40

Hey guys I'm currently using astro a40's with the mix amp and i really enjoy it, not to many wires, anyways the headset is my cousin's he is making me use it while he is off for university, I'm going to buy my own headset but i don't want to spend 249.99 is their anywhere i can buy it for like 150 under? is their any other headsets like the a40 with a mix amp ? maybe the tritons i like the astro mix amp

any suggestions maybe the a30?

#I am an Astro fan, and Microsoft was recently selling the A30s wireless sound system w. MixAmp for $150. Not a bad deal.
