I haven't purchased anything off ebay since July but I managed to snag two great pieces today at killer prices. I'll be using the Feedback Destroyer Pro for my infinite baffle subwoofer in the basement and the Panasonic will be paired up with another identical one to drive the new dipole speakers I'm building, which are 3-way active speakers that will require four channels of amplification per speaker.
$155 shipped for both of them. These two would usually run about $210-$230 shipped off ebay, so I got pretty lucky. :D
