Not to be Johnny Raincloud, but everyone should really be careful of all these new posters selling hardware for very low prices. Because MacNN doesn't require a certain number of posts before you can post FS threads in the Marketplace, there have been a lot of people getting scammed lately.
I know it's been said, but I'd really encourage the mods to require some level of activity on the site before they allow newbies to post, and sometimes, scam other MacNN members.
