@ Pokerplayr: Take it easy, man...don't let others get to you. This is almost-exclusively a testosterone field. As a newbie, you're gonna get hip-checked into the boards once in a while by some of the "alphas". Take it, get up, skate away and, when you see your chance, drive 'em through the boards...cleanly.
I started collecting in the fall 2014...immediately, irrevocably hooked! Wife says it's a mid-life crisis...maybe.
I overpaid...really overpaid for some of my early stuff... examples: 120 Euros (plus shipping) for a First Blood poster...$355 (plus shipping) for a Dark Knight Joker "why so serious" poster. But, you know what? I wouldn't change a thing. Those experiences have helped improve me as a collector ... I no longer buy a poster just because I want it bad ... I research ...research...research and research some more...then I set my limit on a poster ... then I stick to that limit... it's worked for me and I've got a nice little collection now that I love and feel good about.
You may have deep deep pockets and don't care about overpaying ... if so, then carry on, my friend, and enjoy. Just don't let others get under your skin...take it and then dish it out ... the forum is more enjoyable, for everyone, that way.
