Just a suggestion, make a poll in your first post. That way you dont have to ask every participant individually which gun he/she would pick.
I'm not sure where you heard that scammers live on the classifieds, but trader ratings usually keep problems to a minimum. The reason you would be better off with the classifieds is that you will probably find the ones you listed, as well as some of the high end ones listed for a better price. A lot of the times they will come with other extras like magazines, battery/charger and even accessories. Basically you have a chance of getting more for your money. If you absolutely want to go brand new, you'll have more options from our member-retailers as well.
