Submersion Chiller or Refrigerator Question?

[Payson]

I use a counterflow chiller with a recirculating ice bath for beer making. I can drop boiling wort (unfermented beer) down to less than 50 degrees in just the time it takes to cycle through. It takes a lot of ice. The alternative, like you mentioned is an immersion chiller. Unless you have super cool well water you're limited by the temp of your tap. A pre-chiller used in conjunction works well but it too would require a lot of ice. I lager beer using a cabinet that cools based off of a dorm fridge. It's similar to the son-of-a fermentation-chiller mentioned earlier except a good bit of the work is already done, IE: it has a thermostat and requires no ice. Here are a few pictures of what I'm talking about: http://www.flickr.com/photos/raisingale/sets/72157622039510272/ The lager cabinet has the fridge attached via two 5" PVC pipes that pump the cool air into the cabinet below.
