When I saw the Flashcam on CSI, tonight (about an hour ago, for me), I thought, "hey, I remember seeing a link for that on CPF!"
Yeah, I never wanted an M4, before, and don't anymore, but when I first saw Grissom using it, I was like, "hmmm, I might need one of those...". I didn't even know what it was until I asked a question about it here and someone else knew. I said that I don't want one anymore, but now that I think about it, I do always check out the FS threads that mention them, and sometimes will check eBay for them!
