Andy,
Listed below are bullet points outlining some features of both bc's. The Epic would be considered our "entry level" (price) weight integrated bcd. Really a great value. The Vector 1000 is built a little tougher, has more trim, bells, and whistles yet costs a few $ more. Hope this helps, if you need specifics on anything please post back.
