Reddit mentions of 3ct. - 3 Piece Airlock with #6.5 Stopper - Set of 3 (Cylinder Airlock)

Airlocks are easy/cheap but you can make your own with a hose and water in a bucket

The sanatizer is also easily done and cheap but you can use a highly diluted solution of bleach and water but dont want any bleach in your brew.

The yeast do all the work, put it in a closet and check on it, works easily and well. I haven't done a mead yet but about 5 batches of cider and 4 of beer in 5 gal. carboys, investment costs at first for a full set up can be high (but still sub $200) to make your brews/ciders/meads in 5 gallon batches.

Check out /r/homebrew good people over there and excellent information to get you into it if you're really interested in a hobby you can really enjoy.

Depends on the ingredients of the beer, but it really is basically just that. You just need a cointainer and something then to keep oxygen out. Those things cost several dollars only. They're little plastic/glass airlocks you stuff on top of the bottle:

Wine's easier to make though.

Haha, considering you don't know anything about brewing beer he probably could have done a better job explaining some terminology. Gravity doesn't refer at all to the weight or mass, gravity refers to the sugars present in the liquid and therefore the potential ABV. This is what you must measure to determine how alcoholic your beverage will become, and ABV cannot be measured in any other way. Gravity can be measured with a hydrometer, and must be measured before the mixture has fermented at all. Potassium sorbate can also be found on Amazon if you aren't near any brew supply stores, but while cheap you'll probably have to buy around a pound if you want it shipped to you for free.

Lastly, as for equipment you'll need an airlock, an airtight glass jug or plastic bucket the airlock can go into, and some kind of siphon to get it out. That should be good enough for a basic setup.

That's actually not bad but as mentioned below, a decent pot will go a long way. I bought a 30quart turkey fryer and put in a ball valve and that's been one of the best upgrades I've made. I have a fermentor now, but I got some free 6+ gallon food grade icing buckets from my grocery's bakery. Spigots, air locks, and bottling wands are $6 on Amazon. Tubing can be found pretty cheap online or at LHBS/hardware store.

Kettle - $25

Ball Valve - $22

Bazooka Screen - $9

Buckets - Free

Spigot - $6

Airlocks - $7

BIAB Bag - $5

Bottling Wand - $5

Capper with Caps - $18

Various Tubing - $15

This doesn't include your first beer kit, but you can pull off an all grain BIAB as long as you've got fire. My second favorite piece I own is my mash tun which is just a 10 gallon cooler with a bazooka screen and ball valve. I don't bottle anymore, but I feel like if I were to do it again that's all I would need to start. Oh, and a thermometer and some StarSan.
