Here's a link from Oregonlive which interviews several nano breweries: http://www.oregonlive.com/mix/index....e-batches.html

I've done a lot of research on this subject, and it seems to me that the people who think it costs 200k+ are assuming that you are opening up a brewpub. Serving beer on tap, food, with a brick and mortar building. They usually quote construction costs in that 200k budget they mention. If that's the case, then yes, 10k won't even pay rent for a year.
If you are looking to brew beer in your garage, and distribute it yourself (btw, OR and WA allow you to self distribute) than 10k is feasible. You will have to keep your day job, and you'll likely brew everyday. The Internet is full of stories about breweries who started with 1bbl and upgraded to 3, then 7 then 15, etc etc. It can be done. It's a lot of hard work though.
If you plan to sell bottles, don't forget about all the extra work that goes into that. You'll be filling and labeling bottles by hand, unless you want to spend 20k on a used automated bottler.
I once looked into going the keg route. My Pale Ale recipe would cost around $50 a keg. Micro brewery kegs sell for around 130-150 (see: http://www.maletis.com/beer-dock-sales.php
) So let's say a keg cost me 75, I could still sell it for 130 and make some decent $$.
Run the numbers. Shop around. Look for used equipment. Think of EVERYTHING and EVERY possible scenario. Write up a business plan. If it still looks good. Go for it!
