I highly recommend making a simple, copper immersion chiller. I watched a couple of youtube videos until i was comfortable and did it. I just used the lowes 25' copper coil and formed it around a can (I used a scuba tank) and used a small, hand held bender to form the in and out lengths. I also got fancy and put some hose connectors so i could break it down for storing but that is totally optional. It works great and i love the fact I made it myself. Total cost was somewhere around the $25 - $35 range.
