I eat brown rice at least 4 times a week, and would be utterly lost without my
Zojirushi 5 1/2 Cup Neuro Fuzzy Rice Cooker and Warmer. I don't have enough posts yet to post a link, but Amazon has it in stock (ASIN number B00007J5U7).
It is pricey, but I've had mine for just 2 months and already consider it worth every single penny. It cooks rice better than any other cooker or method I've tried, and brown rice ROCKS in this cooker!! I buy the organic brown basmati rice from Costco (it comes in a burlap sack), and it cooks up consistently fluffy with separate grains each and every time. It takes about two and a half hours to cook roughly 5 cups of brown rice, but all you have to do is set the machine and walk away. The machine also has a "keep warm" feature that keeps the rice nice and hot for up to 12 hours after cooking - I had heard that the brown rice deteriorates as it sits, but so far have had occasions where the rice was kept warm for about 3 hours, with no noticeable change in texture or taste.
The cost of the cooker isn't even really a factor if you're going to use it multiple times a week - it would cost more to buy the frozen or pre-cooked packages long-term than to make an investment in a quality rice cooker. I highly, highly recommend it!!
