[SOLVED] cMOS inverter circuit question

Hey guys I have the following circuit; its an inverter using transistors

http://img716.imageshack.us/img716/7609/circuit.jpg [Broken]

Im trying to figure out what the voltage value of Vin should be WHEN both transistors are in saturation mode. I have realized that if they both are in saturation mode then they will have the same current going through them - but when i use the drain current equations I'm left with a variable that I cant lock down in terms of Vin, namely the voltage across the gate of transistor 2 (Vgs2).

Can anyone help?

Nevermind, I realized that Vgs2 is equal to 0 at all times.
