hard to say w/o knowing the price you found it for.
This is a good buy IMO: http://cgi.ebay.com/ebaymotors/KICKER-DUAL-12-LOADED-COMP-2010-C12-VENTED-SUB-BOX-NEW-/130401842233?cmd=ViewItem&pt=Car_Audio_Video&hash=item1e5c8e3439
It's not "Kicker"'s box, but it should yield about the same performance.
