Well...actually some K2/100's draw more power.  Mine does take up to 20 
amps on some bands.  The 35-amp Astron runs all kinds of things in my 
shack and is also usable with another transceiver that I have that does 
take more current.

The advantage of the linear supply is: no electrical noise generation. 
Disadvantage: must be at least 2 feet from K2 due to magnetic field.

The advantages of the switchers are:  physically lighter and smaller, 
smaller or no magnetic field.  Disadvantage: possible electrical noise 
generation.

Many people will tell you that such-and-such a switcher is totally 
quiet.  This seems to vary by particular unit.  It also depends on your 
antenna and feedline, and the particular frequency.  I personally am 
sticking with the linear supply.
