just get the nova... then you will have a little extra $ left over to get a sling, a slug barrel, and ammo

i love mine, its tough as nails... supernova has a recoil reducer in the stock... but its just like a cylinder of viscous oil or some fluid... other than that i dont think its THAT much different... if it kicks too much you can get the recoil dampener cylinder from benelli and turn your nova into an almost-supernova
