Having a budget for the freezer helps maintain your focus on models with price tags that fall within your range. Before purchasing, research freezer models on sites such as Consumer Reports to find customer reviews, recommendations and expert ratings of various brands based on their reliability.
Check out online listings of freezers posted by owners, or visit stores that deal in used or refurbished appliances to find a suitable freezer. Conduct a pre-purchase inspection of the unit before negotiating the price. Talk to a seller, and ask about their motivation for selling the freezer. Determine if it has any defects so you can decide whether or not it can still be fixed, and try to negotiate for a better deal.
Once you select a freezer, inspect it to determine its energy efficiency and the functionality of the door seals, and ensure it does not harbor repugnant odors that are hard to eradicate. Upon finding a good fridge, consider spray painting it if color is an issue.
