If you can do a bank transfer from the internet, any exchange that people told you about will do. Ofcourse it will take some days and probably be more expensive.
The only one I have experience with is
https://bitstamp.net but it's an European exchange
Being in the US, don't know which one would be best for you.
Hmm, I thought my bank allowed transfers from the internet, however when I log in to their portal and select Express Transfers, I am only able to transfer money between my accounts. Not sure how to set up online wiring (or if my bank can even do that. I think that's more common over with you guys than it is here)
Drudgeboat,
If you have downloaded the Bitcoin client, I will send you .01 BTC to get you started. It's not much, but it's something

Just post your Bitcoin address and it will be on its way.
The Joint, that is very generous of you, thank you!
