I bought a couple items from this site:
For drying (my feet sweat a bit ) at home - boots and gloves and have the option between heat and no heat.
and for warming my boots on the way there and/or at lunch or when I take a break on cold days
I also have done other less expensive things like:
Throw handwarmers in the boots on the way there then put the hand warmers in my mittens at the mountain. I'll also put the boots on the floor of the front seat and let the heater beat on them to the mountain. Just throw them in the bag real quick, go inside and put on toasty warm boots.
Used the hand dryer in the bathroom to warm/dry them.
Place them in a sunny window at the lodge
Put them over the heat vent at the lodge
The two items I bought from dry guy work great and bought them on sale so it was a little less expensive. The boot dryer is rounding out it's third season and has had no issues. I like it more than the Peet (which I also have) because I can chose no heat (heat molded liners - it shouldn't matter by I'd rather not take the chance). My only issue with the little orange thingy is that when using an a/c outlet, you need to make sure the car outlet is plugged in all the way. If the little red light doesn't come on, it isn't working.
