I find Pspice the best tool. It has many models and you can also build your own. And when it comes down to wiring and layout of components on page, it does a good job with minimum hassle. I also use Eagle because it has a great many pre-drawn components, but I don't find it's user interface friendly.
I have sent a lot of emails to Eagle tech support, but always get an answer, so that is good. I like Switcher Cad III free from Linear Technology for simulation.
If you want only to draw circuits, and not subsequently to use them for analysis and/or board layout, then I suggest you try MS Paint.
You can create your own library of shapes. This, and another instance of Paint, can be opened at the same time so you can copy from the former and paste in the latter.
if u are looking for a fairly easy to use free program id suggest using circuitmaker student version. I have it and it comes with about 50 predrawn circuits to base off of and has many components in library but not as many as those in bought programs of course...its bestto download it in an FTP format but the other way also works...if u need help with it feel free to pm me or ask on here...thx l8er
Also on this subject: How can I post a *.ckt file from CircuitMaker? I lose way too much information on it when I try to convert it to a *.jpg, *.bmp, or any other graphics file. Would zipping it help? All help is appreciated.

You could zip it and then post it, but it would be limited to only those people who have the same package - so it's not a very good idea?. Exporting it as a BMP shouldn't lose anything, then convert it to GIF using a decent grahics package. Don't attempt to use JPG, it loses quality and produces far larger files than GIF for diagrams (also don't post BMP direct, they are un-compressed and absolutely huge!).
Search around for "Irfan view". Its a freely downloadable software package (and only around 200k), which, among other things, can convert BMP into just about anything else.
