This circuit is the one I always use and I have yet to see a zapped MOSFET ;). Diodes can be 1N4148 or almost any fast signal diode (never a rectifier such as 1N400x) and a resistor of 1K-10K is enough. IIRC SMD BAV99 has this exact configuration for the purpose of being used as input protection devices.
