I finally was able to get a fridge using my hoarded Canadian Tire money and gift certificates. I've written up a how-to on the wiki based on my experience today (with the help of MrX's thread here) and based on my own fiddling. I have not yet added a 2-tap tower but I plan to update the how-to once I do.
