yes i do recomend building your own water chiller or letting the people around here build one for you... you can get far better tempratures it will take up less space and probably cost less.

basicly what you need is a decent compressor anything less than 1/12 will not do anything worthwhile as pun has personaly experenced right?.
ok now the rest depends on your funding/technacal ability.
ok so once you have a compressor you need a condensor this is where heat is removed from the refridgerant at high preasure so that it can become a liquid again. a water cooled condensor will not work any better than an air cooled condensor. if your willing to spend some money or take some time to look for one you can get one thats allready made just go down to the scrap yard and look for window acs old fridges and look for a realy good radiator type condensor. if you cant find one it can be purchsed at any hvac place for about 70 dollars for a decent one. now personaly i would not pay that much for one and id make it myself if you have a high temprature torch some copper tubing 1/4 or 3/8 and some sheet copper its not that hard. cut your sheet copper down into your fin size stack them up and drill the nessicary size hole and run the copper tube trhough it then braze/solder it all togeather. now if your somewhat less technacly abled and have alot of water cooling stuff around then make a water cooled one. take about 20' of 1/4" copper and coil it up stuff it inside of a piece of 4" pvc drill holes in the end caps and pull your lead out of there then glue it all togeather. now drill a hole in the top of the pipe at each end and put in a pair of hose barbs. grab a whatever sized pump hook it up to the inlet then the outlet goes out to a heater core or radiator then back to the pump. thats your condensor!
ok now from your condensor you need whats called capilary tube its to reduce the preasure from the high side to the low side. the lower the low side preasure is the lower the boil point of your refridgerant. ok now capliary tube is 3/32 of an inch or SMALLER copper or brass. now slide that about 1/2-1" into the end of the condensor grab a pair of cable snips(dikes, wire cutter, ect) and crimp the side of the condensor pipe off at an angle to make it tight around the capilary tube and then braze/solder that shut
next is your evaporator whic can be 1/4-3/8" copper tubing it doesnt realy matter which one the wider the tubing the shorter your evaporator should be. just coil that up and atach it to the capilary tube same as before. then atach it to the suction side of the compressor and your done.
on the compressor you will have 3 lines. 1 on one side thats slightly larger than the rest thats your suction line
2 on the other side one of which is your factory fill that will be crimped shut unless you have an ac compressor in which case its a nifty valve. and your high side line.
to fill it you will need to add a valve to the factory fill line and probably one to your low side line OR permanatly atach a preasure guage right before the compressor so you can find out the preasure there you want it as close to 0 as possible you dont realy need that guage if you have a realy big compressor that can pull a vaccume. so then add some oil toyour system through the fill valve. then add refridgerant through the same valve slowly add it untill the evaporator becomes cold and add/let out refridgerant untill you reach your optimal temprature.
