know enough about them to really know.

They're usually not much good right next to the antenna (or the radio, if
the antenna is on the radio), but vary in how bad the birdies they generate
are. My MFJ puts out enormous birdies so I'd avoid their switching supplies.
My Astron SS-18 is tolerably low. The payoff is that the switching supplies
generate much, much less heat, and thus use less power if left on all the time,
in particular.
