Again as a lurker I half expected this! When I posted the auction I wanted to stay neutral (even though I thought it looked dodgy to me), in my reply I even said as much. I wanted to try and stay respectful incase it turned out to be genuine.
I can understand that you get people on here playing silly games and people may be cautious to a new member, but please I can only stress this is not the case. Atari 2600 was the first system I had back in the 80's as a kid and I am collecting the games from my youth (along with the other systems / games from this time etc). I search eBay UK daily for the items I'm after (including EU) and simply noticed this pop up. As I said I'm no expert, but I knew what Air Raid was and came here to see what people were saying about it. I thought it would make a good first post, fake or not, as I expected it would gather interest and make a good taking point.
I simply collect the common games I used to own (and am not interested in other games physically), of which I nearly have the lot! In fact another reason I signed up was I that I had been thinking about purchasing a Harmony cart and participating in the High Score challenge you do (I'm a competent player but dw I won't be breaking anyone's records!).
I have a solid eBay account of which I am a majority buyer (I sell once in a blue moon the things I no longer want), I have perhaps made purchases from members on here? I remember buying a nice boxed Defender & Missile Command (I think) from a shop 'World Of Atari' based in Germany if I remember correctly.
And yes I am also from the UK and it is a big place funnily enough, to put it in perspective for US members, I don't even live in the same country as the listing location (I am based in the South Wales Valleys - 30ish miles from Cardiff).
