The cost of my homebrew 1600W (continuous) dummy load was zero.  It was made 
from scrapped parts from my employer at that time.
It was based on four 50 ohm 400W flange-mount RF resistors in series-parallel.  
They can take full power up to 100°C.  I still have a couple dozen spares.
I like it better than an oil-filled DL... no oil to weep/spill and oxidize.  I 
just vacuum out the dust bunnies once in a while. :)
