URGENT limited offer, Paradigm 15 v1 faulty $275?

Hi all,

Would really appreciate any input ASAP as to whether this is a good offer? I am struggling to find the value of this sub in a faulty condition and even in used working condition is quite difficult.
The fix sounds pretty simple, the amp is creating audable hum but works.
I am hoping to get the price down under $200, but either way is this a deal you would jump for?

Thanks
