Here is my list (a blogroll of sorts) of must visit sites for camera accessory junkies!
Strobist
http://strobist.blogspot.com
The most portable way to carry your own lighting studio with you wherever you go. If you ever have a need for learning inexpensive ways to creatively light your subjects be sure to read through their extensive articles and tips. Strobist is one of the top photography sites on the Web!
BTW, my photography teacher from a few years back claimed he originally came up with the strobist technique - I'm not saying he did, not saying he didn't...I'm just throwing that out there.
Lomography
http://lomography.com
Not only do they have cool, trendy cameras - they also have plenty of accessories to use with them. The Diana F+ camera has a number of lenses and adapters that will keep any accessory junky busy for hours. Lomography is one of the hottest new hobbies for photographers, take some time to check it out and see if you don't get hooked.
