i like my shadowcat (except i'd like a little more speed out of it) but i'm getting real tempted by the scepter v. for those who have shot both, is there that much difference between the two to justify the $850 price tag. if so what are the major improvements to the scepter v?

there's no dealer within a couple hundred miles of me that might have one to try, so i'm depending on the experts here to help me out.
