Passionate,
Welcome to the addiction. Look around carefully when tou shop online for equipment. There are super deals to be had very inexpensively. If you are patient and search diligently you can save a lot of your hard erarned coin. I am in the process of building a gas fired all grain set up and really have been frugal and managed to collect all the pieces for around 300.00 including burners, cook and boil kettles and two mash tuns. So it can be cheaper to be a little patient. Several of the brew suppliers already mentioned have some excellent starter kits that will get you going with a good basic set of tools. You will be able to shop a bit and get large kettles off Amazon, Ebay and craigslist. Other items are must buy like Bulkhead fittings and sight glasses, but those are available also pretty cheap from the fitting supplier that advertises here. I cant recall the name off the top of my head right now, but the do a great customer service and shipping job and are very reasonable on the stainless fittings and kits. So be patient and look carefully and you won't ever have buyers remorse.
HTH
