Outlook to Thunderbird

I used Outlook on a PC I had in college in order to access all my email, However I am now due to no longer have access to this computer so I've decided to set myself up with a mail client at home.

The most obvious choice would seem to be Thunderbird. However there is one issue, I want to be able to import all my old mail from Outlook.

In Thunderbird the import option only allows for importing from another mail client on the same computer, even though I have the *.pst files.

So looking for some advice as to what to do, some options I've considered are:
1. Use another mail client which will allow me to import my pst files; not really aware of others but open to suggestions
2. Get a hacked copy of Outlook and use; prefer not to do this as don't like to be illegal if I can avoid
3. Above option but only install to allow me to import to Thunderbird; would still prefer to refrain from this option
4. Install outlook express, get it to read pst then import that to Thunderbird; not sure if this will work or not
5. Find some way of importing the pst files; here is where I'm looking for your suggestions, I tried google but so far with no luck

So any advice welcome, just to say I'm running win 7 and thunderbird 3.0.

Finally if I am to use thunderbird would love if I could get it to display the email list the way outlook did i.e. Subject and Sender on two separate lines instead of one, although this is not a dealbreaker.
