I bought the deluxe all-grain system from Norther Brewer:

I have been very impressed by it. The false bottom works perfectly. The Rubbermaid coolers keep the temps steady throughout the process.
The only thing I would do different if I were ordering it again would be to get the 10 gallon system. The 5 gallon system is not big enough for "big" beers.
I am apparently in the minority here as one who is not really very interested in building my own equipment. For those who enjoy doing that, I have nothing but respect. I was very happy, though, to get my kit in the mail and to be able to assemble it and have it work flawlessy right from the start.
