I see you live near Toronto. Check out Hedgehog Ville in Scarborough. You can get Carolina storm wheels directly from them without paying crazy amounts of shipping like you would from the states. You can also look up how to make your own bucket wheel.
But basically: they're extremely quiet (I only hear the pattering of feet), very easy to clean, and there's no risk of health problems because of the way it's built. Worth every dollar in my opinion.
