I use the Astron 20M. It's got plenty of current capacity to power the K2/100 to full output plus some extra for accessories without staining.
Some ops like lots of reserve current and want to be able to power other rigs that demand more current or more than one rig at a time so they opt for the much larger Astron 35. The 20 is rated at 20 amps intermittent commercial service. The K2/100 typically demands about 14 to 18 amps intermittent service (voice peaks or key down CW at 100 watts output) These are linear supplies, very quiet electrically but fairly heavy due to the large power transformer inside. Also, you don't want to put them closer than about 18 to 24 inches to the rig. Most rigs, actually, because the strong a-c field can induce hum in the rig. I run my Astron on a stool under the operating desk. That keeps it away from the rig and saves space.
