As has already been mentioned, it’s best to ask what not to use. Some brands have already been mentioned, but there is more to it and as the subject has already been touched upon, allow me to expand. Matt is right, sunlight destroys hops. In the presence of sunlight there are certain chemicals in hops that will be converted into new chemicals. These new chemical compounds are molecularly similar to the same compounds that are responsible for giving skunk musk its legendary aroma. Clear bottles do not block any sunlight. Green bottles do not block much sunlight. Brown bottles block a lot of sunlight. Do yourself, and any one who might drink your beer a favor - only use brown bottles. Brown crown cap bottles are also the standard home brew competition bottle, if you ever get into that side of things. You can even get brown grolsh type bottles from the home brew store, but who buys bottles? Most micro breweries use the same bottles from the same suppliers. Almost all of these bottles work great. Sam Adams and some of the other craft brewers use similar bottles that I have also used with great success. I, like many others, use the cheap twin handle red capper, and am therefore limited to bottles that have the shoulder below the top because my capper needs that to grab onto.
As far as how to consume enough beer to gather the appropriate amount of bottles between batches: you could loiter around college town recycling bins (a frightening proposition) or do what I did and find a roommate who drinks too much. You can usually find them in the flower beds in the park next to the bars on Saturday mornings. Short of those things you’ll just have to develop a strict regimen of scheduled beer drinking to ensure that you have enough bottles.
