Evaporator Blower A/C ??? HELP??

I am looking to cool a larger setup and need to find an evaporator chiller that is of good quality. They are usally either 2fan or 3fan. I cant find a good retail place anywhere that can help me. I need someone with expirence with the units to lend me some knowledge. Thanks for you time!!

I was thinking about getting one myself. After spending a while looking online I came across some that appear to be of good quality:

Be sure and have a look at their return policy, though:
