Anyone using a free/cheap SPICE that they like?
I keep finding myself handicapped by not having access to one, but I would rather not have to trial-and-error a bunch of them in order to find a decent one.
I used batch-style SPICE back in the day, so I can do that if necessary, and post-process the results. Probably easier now that spreadsheets and whatnot are common.

I thought we had several older threads about this, but only found this one with a search:

Thanks, that's helpful.

Student? When I said "back in the day", I was thinking the 80's...

Here you can find all the additional models

and here
http://valvolodin.narod.ru/soft/extra.rar
Unpack the archive "extra.rar", using the archive RAR
Copy "extra1.rar" which is installed in the directories are LTspiceIV. Typically, this directory is "C: \ Program Files \ LTC"
Unzip "extra1.rar" which is installed in the directories are LTspiceIV
Finish

Thanks for the heads-up on LTSpice. This thing is pretty slick, and seems to do everything that I want.
