I had really good luck with the factory refurbished Canon HF-G30 I got a couple months ago that I've started looking for refurbed in every piece of audio/video equipment I purchase. Here's another good buy. I just ordered one for myself. Refurbished GoPro Hero 3+ Black Edition
Just FYI - another factory refurbished item I got was the Sennheiser EW112 Wireless Mic package. Saved about 30% on that deal. Factory refurbished is the way to go!
