Need suggestion on what to use for traffic counter?

Need suggestion on what to use for traffic counter? I am just curious to see how many people have come to my site today. I actually have 3 new members and I just launched it today. I don't know any of them either!

I'm having an issue with 2 peeps from Canada. They need to have money transferred from their bank account and put into PayPal for chained payments to work. It will take them one week for that process.
