Then buy the cheap one, by all means, but I'd go down to the Lowe's or Home Depot and try one first. It is actually pretty pleasant.
Will a simple (properly chosen) thermistor in line work?
Yes.
Thank you. Time to find some thermistors and do some experimenting on the bench.
I read in an old lighting handbook that if you reduce the voltage by 5% an incandescent will last 2000 hours.

There's an exponential relationship between filament life and operating voltage. For instance, if you run a 100 W bulb at 60 W it will last essentially forever.
