PWM is a better solution, contrary to what was stated earlier.

OK, I stand corrected...
The statement I made earlier "Pelts don't like PWM" is too general and as such not correct. PWM can be used successfully to regulate the TEC voltage as long as the voltage doesn't exceed Vmax and the frequency is kept above 2KHz to minimize thermal stresses. Power MOSFET's are a good way to go.
