[Elecraft] Dummy Load recommendation

[CUTTER DAVID]

I often wonder just how useful a precision dummy load really is in the amateur service.  I picked up home brew dummy load at the club the other day.  It measured 57ohms dc and comprises 4 wire-wound resistors attached in a cluster across the end of the coax.  After lots of disparaging remarks I put it on the VNA and it didn't look at all bad out to 30MHz: nothing over 1.5:1 and no spikes or dips to indicate resonances. I'll have to do it again and make a print-out for posterity. 
I've heard that salt water in a bucket works after a fashion.  
So the question is: how good do you need it to be?
