In the shack, I use linear supplies. As you mentioned, the are reasonably easy to repair if they break, and they're RF quiet.
I got tired of lugging a 30-amp linear supply out for Field Day and other "portable" operations, so after reading lots of reviews and threads on the subject over a spread of a couple of years, I bit the bullet and bought a Samlex SEC-1235M. After three marathon field day efforts, some POTA activations, and a few other trips, I can say that the 1235M is RF quiet and has plenty of headroom for my 100-watt portable station and accessories. I am pleased with the performance of the Samlex.
