I have the 3+ silver which only 120 fps in the WVGA. I didn't really know what I was buying when I got my first gopro, but I want to get another one. Either the 3+ black, or 4 silver. My main reason is both of these are better for low lighting, which the 3+ silver isn't good at.
Still a lot of fun to mess around with a camera you aren't worried about breaking.
