This thread is hysterical. HBT represents a huge brain trust. And here it is wasting synapses trying to figure out how to squeeze a few dollars. This is not what homebrewing is about. Maybe a new hobby? SWMBO might get you a metal detector? There might actually be a RETURN on that hobby!
I agree that saving a few bucks is not what homebrewing is about. But, it is easier to justify if it is not costing TOO much money. Because I am able to brew for between $20 and $25 a batch, I have no qualms about brewing every weekend if I feel like doing so. If it cost me $100 to brew up a 5 gallon batch it would be a very different proposition. Of course, I tend to prefer session-type beers, so I can make my preferred beer for $25 a batch. If I was being forced to make beers I did not enjoy drinking (and/or was not proud of making), my view would be different.
