I've been doing 5 gallon extract kits for almost a year and have done seven five gallon batches. I was hooked after the first one for sure. Recently my father in-law purchased a Minibrew 15 gallon conical fermentor for me to, "make him lots of beer..." I will be using a 40 or 60 quart ss stock pot to do my first 10 gallon batch very soon.
