Hey to all, I'am a DIY'er myself,if I can make it I'am not going to buy it.Most of the time its better than buying it.With that said, I get catologs from every where and one I do buy alot from.surpluscenter.com,they have a mini refrigeration unit that is 16"x13"x20" originally built for desktop soda fountain.I like to fell over at the cost.A whole $29.95 plus shipping,1/2hp,115vac motor,3.2amps it has a flexible cooling jacket that is 33"x8"1/2 that could be wraped around a res or the res sitting on it.They say it has solenoid valves,striring motor,pump and miscellaneous parts with it too.I say if you are a DIYer this is a good find for a res cooler and extra parts too boot.I buy fans and things from them. The 200cfm fan has been going for 8 or 9 months now and doing great too.If you are a DIYer check them out.PEACE
