Good electronics simulator for beginner?

I can also recommend LTSpice. Real time and flashy doesn't mean it's professional software. LTSpice is very basic-looking, isn't real time, but is incredibly flexible. If there's any analog chip you want to simulate, just google "[part number] spice model" and, odds are, you can find what you need.

I've used LTSpice all throughout college for varying levels of electronics classes and it has never failed me. It's great to learn how to use SPICE software in general since many of them work very similarly, and LTSpice is free and especially good in my opinion.

I chose LTspice when I commented above.  Yes, it's excellent.

But one level up, at a system view, MATLAB and Simulink do an excellent job.  Instead of dealing with individual op amps as integrators, I can just plug in an integrator to a model.  In effect, I can create an analog computer solution to a system.  This is clearly the domain of physical analog computers but they're not in favor at the moment.  Obsolete...  Maybe "old school"...

BTW, LTspice does a nice job at the system level as well.  I have some models of integrators that I can just drop in to a schematic.

There is an Electronics pack for MATLAB but I haven't played with it. 

The reason I bring up MATLAB is that there is a concurrent thread about explaining a capacitor.  I wanted to graph the charge and discharge curves and it is easy to do this in MATLAB.

I'm not sure what you're asking for. LTSpice isn't real-time, whereas other simulators are. Seeing how things move around can help a lot, especially for beginners.

MATLAB is not cheap.  Are using the HOME version (which is reasonable)?  Octave is cheap (free...of course).

Thanks for the input folks!
