Wizards of the Coast now has the issue archive for the issues of Dragon & Dungeon magazine that they have produced so far. While the content that WotC has produced may not have been well received by all D&D fans, especially those that want the print versions back, they have put out some good 4e content.
So check out the archive and get the back issues you missed, while they are still free.
Speaking of Dragon magazine.....
To fill the void left by the transformation of Dragon magazine to pdf format you should check out Kobold Quarterly. They not only offer print subscriptions, as well as pdfs, but to keep the spirit of Dragon Magazine alive, they will apparently be supporting the current 4th edition of D&D.
