OK, Thanks for answers to my Sanguino question. Is there any place where you can cheaply buy (<US$10) an ATMEGA644 with Sanguino bootloader. I will only need the chip. It seems that this chip needs same support as ATMEGA328P to run duino environment (5V DC, 16MHz crystal, caps etc.) I will need to get serial cable/FTDI chip board for other stuff anyway.
