The Eye TV Hybrid, from Elgato, is a nifty little device that allows you to watch and record TV on your Mac. It normally sells for $149.95, but you can get it for $99.95 through this promotion if you buy it by December 31st, 2008.
I picked one of these up at Macworld 2008. I don’t use it a tremendous amount, but it is very handy, and I’ve been happy with it’s performance. I recommend them.
As a side-note to anyone attending Macworld in January, Elgato will be there, and they usually offer this same price during the Expo, along with discounts on their other products.
