I'm not sure if this is the right place to post this so feel free to move it if needed. Although I've been doing this hobby for quite a while, I've never had the opportunity to visit any of the AMP in Centreville, IL. I'm just wondering about prices, do's and dont's and any tips people may have. I've read reviews and it seems like all of the AMP there are about the same. I just don't want to walk in like a noob. Thanks for any information
