Transistor circuit simulation

[rcollege]

Are there any simulation software for analog devices such as transistors?
I'm not interested in IC's...just creating class a circuits.
I have Multism by Analog Devices...but the free download has such a limited transistor model selection, and I can't seem to add more models.

Yes, I'm looking for a free program (maybe too much to expect) but I could care less about IC's, saving simulation records or PCB layout. Just saving the circuit. I am window based...
Would it be easier to find a "amplifing wire"?

Thanks all!

LTspice is probably the most used on this Forum.

There s lot of available transistors models, just google a little.
You can add most of them to your simulator s model library, undoubtly..
