I have two boarders ready.

The two board can go to about 280 watts low end setting

and to about 500 watts high end setting with the quiet fans


They are a bit more efficient  then the one board. say 85 watts vs 90 watts a th

Shoot me a pm if you want 1 or 2 of them.

Since you are in USA

 I can do

About 190-210 for 2 units with 2 psu's

About 170-190 for 2 units with 1 psu  please note if you do this and hook both units up to 1 psu you can still use 120 volts but you would want to go lower speed as the psu's on 120 volts prefer to stay at 700 watts or less. So you would need to set to about 4th each unit and use 700 watts


About 150-170 for  2 units and no psu.

I forgot if you are west coast or near me in Howell,NJ. thus. the price range of 20 bucks is for more shipping cost to west coast.
