replace arduino mega chip

ATMEGA1280... sorry i wasn't clear.

I have no problems with soldering throughole and the larger surface mounted parts but i do not feel confident to solder a ?10-15 ATMEGA1280.

edit: programming the bootloader will not be a problem as i have a stk500 board from atmel with various programming options.

edit 2: the arduino draws 700mA at 12V. Strange there isn't any smoke coming out... :-?
