I recently purchased a NewAir AC-*******E-BL 14,000 BTU online with Air-n-Water.
I haven't completely assessed why the it was discounted, but there seems to be cosmetic damage to the baffles on the air intake vent. In any case, I seem to have obtained a $400-$600 device for about half that price.
I am still learning the intricacies of the controls, remote control, water drain, and portable operation. However, we had a four-day heat wave soon after receiving the item, which allowed me to test it. It seems to be working well.
My teenage daughter assessed that "we already received our money's worth" by giving us comfort during some miserable SoCal weather. That is good enough an endorsement for me.
