LTSpice is FANTASTIC for switchmode stuff.
PSPICE takes much too long to run switching power supply simulations in the TIME DOMAIN.  LTSpice works SOOOOO
much faster for switching time domain sims, plus its free!

LTspice is great for switched mode stuff..

All the decent circuit modelers take a bit of getting used to, but once 
you've figured it out, it's great.  For straight linear circuits, hand 
analysis works for simple stuff, but once you start getting into things 
that turn on and off, a decent time domain modeler is invaluable for 
getting an intuitive understanding of what happens when you change 
things like component values.  That is, short of blowing up parts on the 
bench.. although nothing like getting the timing wrong on a high power 
h-bridge and *feeling* the effect of shoot-through from the explosion, 
and having your co-workers come in and ask, "what was that?" as the 
smoke rises.  Accidentally cooking the gate of an RF FETs is not nearly 
as satisfying a learning experience.. the amp just stops working and 
draws too much current on the gate supply.
