Were you able to find what you're looking for?

Hey guys,
We have an 8-year-old refrigerator in our home, which is small for us now. I also found that it does not cool too well now. So I'm planning to buy a larger one. I found various models available in the market, but the price range of a new large refrigerator is somewhat I can't afford now. Basically, I'm looking for a larger refrigerator which has a really good freezer and can cool evenly. A few of my friends suggested that there are firms which provide the used true commercial refrigerator, and it would be better to approach them to get a refrigerator under budget. So I'm looking for such firms which provide used refrigerators. However, I would like to hear from you before making a final decision. What should I look into while buying a used commercial refrigerator? Please share your suggestions and opinion on this. I would be grateful for your thoughts on it.
