Either way will work. Variac is huge and weighs about 30lbs. You can wire it to power bunch of stuff. Like a power strip to power several radios. And you don't need a large one as it will likely be a radio at a time, so even 250 VA would do, let alone 500VA (that I have). Unless you want to do home roasting, espresso and listen to radio at the same time.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
