Which simulator(s) do you have installed?

[toprob]

Here's a quick poll to let us know which simulators you actually have installed, and use. Please don't include any simulators you own, but don't have installed.

Question 1 is pretty simple -- if you only have one simulator, tell us what it is, if you have more than one, which is your favourite, or most used? I'm aware that your favourite might not be the most used, or that you might have two favourites, in which case, you'll need to choose your MOST favourite:)

For question 2, let us know any any other simulators you have installed, and still use. You can select more than one. If you don't have any other simulators installed, or you no longer use any installed simulators, select the last choice.
