What Should I Giveaway? A Nexus 7? Headphones? A GoPro? Or just some iTunes and Amazon Giftcards?

I have already posted a Youtube video on the same subject (see below), but with the start of the giveaway only about 15 days away, I really need some more input. Basically here's the deal: I'm planning on doing a giveaway in December to celebrate the end of the year as well as me reaching 1,000 subscribers. However, I need your help choosing what I should giveaway.

Some of the prizes I am considering...

I am thinking maybe something like a Nexus 7, Beats by Dre SOLOs, a GoPro White Edition, a pair of V-Moda Headphones, or maybe a pair of the Audio Technica ATH-M50s. All of these are in the $200 price range (which is about how much I am looking to spend), so if you can think of any other things you'd like to win let me know. I am actually right now leaning towards not giving away an actual product and just give away some iTunes or Amazon gift cards instead, but let me know. And remember of course to subscribe to my Youtube channel so that you will know when I launch the giveaway and make sure to enter right away.
