mtGox is how I got my coins. All the other ways I tried became non-options just before I could. I would have bought a lot at $5 if it hadn't been for intersango dying. I resorted to bitcoin central which became my go to exchange which then got hacked and disappeared for ages. Eventually I bit the bullet and wired to Japan.
Intersango's break-up with metrobank is the reason I'm not a bitcoin millionaire
I spent the whole of 2012 wanting to buy loads but not wanting to spend insane amounts on bank transfer fees.
(edit: the irony of handing cash to a bank to buy bitcoins was too much for me to bare, so I didn't do it until 2013. Got in before all the fireworks though
). Also, yes MtGox taught us not to keep money in exchanges, as did Tradehill, bitcoin.de, bitcoincentral, bitstamp (even though most of those services eventually returned their users coins). Apparently no matter how many times we learn this lesson, it has to get retaught!
