If you know anything about sleeping bags you will know that a 0 degree bag is really a 32 degree bag the ratings never stack up.
Are you going to backpack in? Or is this essentially car camping? If the latter you can save lots of cash by simply getting a heavier bag. Warm + heavy = cheap. Cold +heavy = a little more. cold + light = spendy.

Not true AT ALL. Sure if you buy the Coleman weekend warrior sleeping bag at your local Walmart, you'll get that kind of performance. Many quality sleeping bags today are rated using the EN system. You should research it. I have a 20* bag that is EN rated and stay plenty warm when the temp hits 20*-25*. I would actually take it below 20*, but that's not for everyone.

Sval is right; bags that are not EN rated and say they are a "0 degree bag" may not be at all comfortable at that temp. One of my friends went into the November Idaho hunt in a -10 degree Marmot bag and they received six inches of snow overnight while staying in a kelty tarp hutch; guy was miserably cold. Eyeguard was in a 0 degree REI bag next to the guy and was perfectly comfortable. Not all bags are created equal. I have a Mountain Hardware UltraLamina 0 degree F that works great for me... next thing to figure out is if you can get a comfortable night sleep in a mummy bag... mummy bags are more form fitting so can cut some weight/bulk, but its not worth it if you feel claustrophobic and can't sleep.
You can get bag liners that add 10 degrees or more for each one used. They are light weight. Also, I've always found the coldest part of sleeping bags is where the bag contacts the ground, so a sleeping pad makes a huge difference.
