Don't always comment on stuff like this, but I figured since I live on EE, I'll add my 2 cents. I've made, I guess, 300 or more deals of all sorts; scopes, rifles, shotguns, computers, reloading stuff, a couple of gps, and everything but the kitchen sink. I've bought, sold and traded. I can't say that all deals have been perfect, you're bound to run into something. For my very first deal, a member accepted a trade from me and I neglected to say that the muzzle of the rifle was chipped. At that time, being somewhat naive, I didn't think it affected the rifle. To his credit, he gave me a positive feedback and did not mention that I failed to say this. I still owe him one. CGN thrives because of gunnuts like dusty61. Since that time, I've tried to fully describe any product I have for trade or sell, and even then, I've learned that what may be unimportant to me, may be important to someone else. I guess what I'm trying to say is full disclosure and open communication would be key in any deal. Some guys like to talk about it, some just say "I'll take it", either way, I try to disclose all that I can.
Thanks to all who I've dealt with, it's been a pleasure. And Merry Christmas!
