As others have clarified, what I meant was that all grain brewing (assuming you do more than a very few batches which would make up for the cost of the cooler, etc.) can be cheaper. Of course, there are suppliers who will be happy to sell you a bunch of expensive stuff. On the other hand, there is no reason you couldn't boost the cost of extract brewing by using a Blichmann. They are very nice looking kettles - don't get me wrong. But they are not required to brew all grain.
I'm with Denny on this one though. It all about the brew, not the bling.
