I had the same sub I paid $799 for it in 1999 as it was none new stock.
Mine said 165w also.
I had the same humm issue. I sold it last year $120
It sucks, that electronics depreciate so much in value. I paid $2000 for a Pioneer SC1527 two years ago and got $900 for it this year.
Anyways that said, I just bought Two Energy ESW-10 subs for $249 each on sale at Futureshop a few months ago.
Plus the fact you can get a new EP-175 which is comparible for $550. With new technology and **new** no humms with warranty also I think $250 is a bit much.
It is kinda of like buying a $75,000 hummer and asking $35,000 for it 15 yrs later
Good luck though.
PS To you it is worth more to others not so sure it will be that way
