watch out if you buy that one from northern you'll get a catalog every week. ha just kidding!! i think i paid 65 or so for mine it was like new but used on ebay. i only mess with 250's or 292's so i only use one of the drivers, i think it's #2. you will also need the extention if you will be doing a inline 6 and the plastic cone to center it. i'll be the devil on your shoulder- buy it, buy it.
