I am a swing top bottle whore. It is the very 1st thing I look for when beer shopping. I have found you can buy empty bottles like the EZ cap brand from your LHBS or you can empty your own. The best place to get these is from a craft beer bar that has swing tops. I got LOTS for free that way.
IMO you want the amber (Brown) ones. They are the ONLY color glass that will protect your beer from light. Florescent is not as bad as direct sunlight but will still screw up beers quick. If this does not concern you then it does not matter.
I have a case of the 1L Ez-cap, and Howe Sound 1L I have a few (maybe 4) cases of the 22oz German Schwartz beer that my local grocery store carries. I also have some specialty ones (I am going to post up a pick of my last finds in a new thread...) from Holland, Ireland and Germany.
I use the green Grolsh bottles for carbed up sweet wines, like Skeeter Pee. Wine can still get skunky but not like beer will or as fast!
If I have my way I will only ever have 22oz bombers to cap and swing tops everything else is for a comp or the recycling bin.
