I recommended this one to a friend becaus the fittings alone can cost you $50. This has it all for about $100 shipped. If you using a big burner you will need a 1/2 inch supply or better. I have tried to run one of those big burners on 3/8 like bbq run on, and it wouldnt give me a good flame. I bought my 20ft 1/2 inch hose from teja as metioned above and my Connectors from Mcmaster Carr years ago....but the amazon one seems priced good.
