Which speed/temperature probe system should I buy?

Does anyone have experience with the Fish Hawk TD? Looks like you attach it to your rigger or line and it will record temp and depth- you have to reel it in to see what it recorded on the way down but for the price it seems like a good option. It retails for around $150.

I don't have a temp depth probe but am considering it. The TD price looks attractive. I'm interested in what you all with experience think. Thanks in advance.
