100 to 150w car inverter with usb support for mobile charging

[pgr2002]

I am looking for a good circuit to be built by me for using in the car. I am interest in 100W or 150W car inverter which will convert from 12v DC to 220v/240v AC and also a USB for charging mobiles/ipod/pda, etc. I am unable to find a good one involving the both. Did anyone come across such a circuit diagram, please let me know. I have seen many such commercial ones in coke can shape or otherwise. But building one by self is more satisfying than purchasing.
