Speaking of test equipment, I thought I should give a shout out for these guys at Ridge Equipment up in Maryland USA... IIRC. I bought a dummy load from them and they shipped fast and they answered questions promptly. Good people from what I can tell. Good prices on some stuff too. Mostly retested used stuff but good from what I can tell.
