The best Euro - Dollar conversion program?

I have searched for hours on www.google.com for the best and fastest way to converse euro's to dollars or vice-versa.

There are lots of programs on the web. But does one stand out?

My personal top-3:

1. Just let google do the calculation! Try it yourself: enter:  "150 dollar in eur"
2. The X-rates calculator, handy little flags!!
3. ADVFN, both graphs and possibile to calculate

For money-graphs you have check Google Finance
