I'd say it's a fair deal, but not smokin'. You're going to need around 40 for a 5 gallon batch, though. Assuming you can't "break a case", that's $80 that you could put towards a basic keg set-up. It depends what you want to do / how you see your brewing process evolving. If I were to do it again, I'd still start with bottles, but I'd spend as little as possible. I'm thinking PET or snagging someone's unwanted bottling set-up.
