After years of thinking about doing it I finally jumped in back in Sept/October. I do extract brewing right now and have 2 bottled w 2 ready to be bottled this weekend. The first two have turned out great. My outlays have been as follows:
Midwest Supplies:
10/26/12 $119.18 Hops yeast LME/DME (Enough for 6 batches)
10/5/12 $169.14 More Grains, Yeast, Fermenter, Extract
9/26/12 $196.93 Brewing Starter Plus Kit + Extra Cleaner
Bought some bulk hops for about 35.00
Bought a larger pot, capper, bottles, 2 kegs, like 50 various pint glasses and misc. items for about 150.
So I'm sitting around 700 in the last 3 months. But I also have a lot of ingredients left even after 4 batches.
Luckily I got 200 in gift certs for the LHBS for x-mas. Not sure what I'll use it on but I'm excited to get to St. Louis.
My next purchases will be a burner, larger pot w possible thermometer/drain built in. Wort chiller. Also a CO2 tank and eventually kegerator.
So between those items I'm close to another 500 easily.
