The deluxe kit is what I started with last July. I got the Better Bottle option for the lower weight and better safety over glass carboys.
You can probably shop around and get all the same pieces for less but I felt it was the most complete kit for the price. That saved all the work on figuring out what I would need and where to get it.
But be forewarned, this is just the beginning. I got another 6 gallon Better Bottle and another ingredient kit within 2 weeks. And 8 months later the equipment buying is just now slowing down. I have just a few small additions to make to my gravity all grain setup.
