If its just for HD, I'd stick with what you have. I mean how many rounds are you going to fire at across the living room distances? If its a toy, I'd buy a Saiga. The other selections are excellent choices, but I know you don't hunt, and unless you shoot skeet where the above mentioned guns will take a longer barrel, I just don't think they offer enough of an advantage to be worth the cash. If you want a range toy, you might as well get something that will take a twenty round drum. If you want to kill some SOB I'd stick with the Mossy 500. Just my .02.
