i literally JUST ordered mine from that ebay seller a few days ago..already in my hands. in the box, brand new. power cable and fuses along with it. personally, i think its the best way to go....
be mindful that the low tuning is only at 50Hz, might take away from some of your lows...just take that into consideration when u run your rca's to it. maybe end up running ur lows straight to your h/u instead.
