If you go into the hobby to save money, you will start with a cheap kit, which will result in lousy beer and a swift end to the hobby. That just creates one more person (+1 for every friend who tried a bottle) telling people how lousy home-brew is.
I think the real cost of starting the hobby (based on figures from thehomebrewcompany.ie) is as follows:
