I have both the 10/22 and the 500. I was having to think about all the on your mind and all I can say is that Im glad I own both ofthose models. There's so many options foe both of these guns that you can spend as much customizing them as it costs.
I paid $189 for my 10/22 and plan to get another and set it up a completly different way. I may even do one as a bullpup.
