I've used those flip top bottles from World Market and they're great! The ber conditions just like in a 12 oz. bottle. the great thing is the price, you get some nice sarkling cider or soda to drink first, then ou end up with a perfect 1 liter serving of beer. I've also re-used one of those Coors refrigertor kegs that use a CO2 cartridge. They're not supposed to be reusable, but all you need to do is open the top, sanitize, fill with fermented wort and fill when you're bottling the rest of your batch. When the beer is ready youjust need to replace the CO2 cartridge (get a 16 oz at the LHBS) and you're ready to go. The best thing since sliced bread (or homebrew). There are lots of videos on Youtube so check it out.
