The best I've found is the smaller D-handle gardening/utility shovels (the ones with an ~ 18" handle). They wont move snow like a dedicated snow shovel, but a true snow shovel is typically useless when it comes to ice and dirt. A long the same lines, the folding military style shovels aren't nearly as durable in my experience.

I've seen them selling for $10 at Home Depot and Tractor Supply, which is a real bargain:

I never take it out....in the summer it's useful for off-roading and in the winter it's useful for snow. Just make sure you have it secured so it doesn't become a projectile inside your vehicle.
