Personally, I am checking blockchain.info at least 3 times a day for my transaction, and I will post here as soon as I receive it.
You should check out bitcoinmonitor.net. There you could set up your address and, for example, get an email once a transaction comes in. Depending on what mail client you use, for example Thunderbird, you might setup a soundfile that is playing once an email from bitcoinmonitor.net comes in. Thats the fastest way to get informed.
