Gun Shopping Question

http://www.thebassbarn.com/forum/images/icons/icon1.gif Gun Shopping Question
I'm going to the Gun Show @ the NE Philly Armory this weekend.

I want to by a Black Gun ie; AK-47, M-16, AR-15 ect.

I have some good knowledge on hard ware and MSRP pricing.

But I can only afford used.

I would like to bone up on the used price market so I am educated enough to negotiate a reasonable deal on Sunday.

Any websites that will inform me of realistic prices?

I don't want to get taken.

Any help would be much appreciated. http://www.thebassbarn.com/forum/images/smilies/smile.gif

Don't really know much on the topic but there is a magazine/paper called The Shotgun News. They have alot of weapons like that in there, it may help I'm sure they have a website.
