So thanks much to every one who posted their advice and experience, it was greatly appreciated!!
In the end what I decided to do was the simple ice-bath. I didn't add anything inside the wort. I simply filled up the kitchen sink with water and ice, stirring both the ice-bath and the wort to help with the heat distribution.
In the end, it took me about 25 minutes to go from boiling to 70ºF. Myself, I want it faster.
I think for the next brew, I'm going to double-team the wort. I'll do the ice-bath, but I'll also go to Home depot and buy some copper tubing, make a chiller of my own. I'd like to get the cooling down to under 10 minutes (ideally 5).
