^^^^^

The above worthless trash known as "multisim", used for simulating circuits costs 905 EUR and

1. Doesn't have a linux version
2. Is missing 90% of new commercially available parts
3. Doesn't have a method of easily adding those parts (except manually, 1 by 1) (as far as I know)
4. Has garbage UI (you can only undo 4 times) (adding or removing a single component can easily use up more than 4 moves)
5. Inconsistent simulations (making the sims work feels like trying to appease a capricious God to not curse you with famine)

The free open source software (qucs-studio) seems to have none of these problems, though I have barely used it.
