Walmart offers the Nostalgia Electrics 4-Quart Bucket Ice Cream Maker in Blue, model no. ICMP400BLUE, for $19. Opt for Site-to-Store pickup to avoid the $4.97 shipping fee. That's tied with our February mention and the lowest price we could find now by a buck. It features an aluminum canister, electric motor for churning, plastic bucket, and plastic dasher.
