Are there any good products for brewing large quantities, half a gallon or more, of iced tea at home?



I’m a big fan of quality, home-made iced tea. I usually just boil the water in an 8 quart sauce pan and use standard tea bags, then pour the tea into a pitcher after it’s finished brewing. But now I want to experiment with loose teas that are available in bulk at a local health food store. I do know that some people recommend using a coffee maker to make tea. I’m asking whether anyone can recommend a product on the market specifically designed for making tea, iced or hot?
