I would say it depends on how much YOU want to spend. You need to ask yourself " how long do I want to look at this or keep this furniture"? If your a person who likes change in their life, often…I would not spend much. The ones at Home Depot will do fine. If this furniture is something you want to keep for a long time then the more money you spend will buy you a better longer lasting set of furniture. The cost will be in the metal it’s constructed of for durability and in the fabrics for weather proofing and durability. Once you start shopping around and talk to sales people you will start to get a good understanding of the product you want to buy. I would shop a range from the self help (Home Depot, Lowe’s, etc.) to the better garden shops and even some furniture stores carry garden furniture. Something else you may consider, when you are shopping around and there are other people looking at these sets also, talk to them and ask them for their opinion and if they have tried other brands. To do this is not uncommon. You might also find a web site where you could look for comparability like a buyers guide.
