It looks to me like some of those kits are pretty complete, including a glass carboy. I've never used a glass carboy in my 8 years of brewing and never intend to. Many of us are moving away from secondary entirely and after seeing the thread on the injuries sustained when that carboy breaks I don't want one in my house. I bought the basic kit like mentioned above, used the stock pot I already had, added a recipe kit, and I was brewing. While a chiller would be a nice addition, I've managed to make a lot of good beer without one. I have added several fermenters to my basic kit. It's hard to be patient and let the beer complete the ferment when you only have one fermenter but being able to brew another while waiting makes it easier.
