yeah, all those links there should get the ball rolling.
personally I feel if you want to keg, you need to get a chest freezer or a fridge to keep things cold.
I'm a beer snob...beer never belongs in plastic (after primary at least )
plus if you put it in those 2 liter bottles, you have to sanitize them first, and they're oxygen permeable, and usually clear...all things that can skunk beer unless you're planning to drink all that beer within 24 hours.
i mean, if you're gonna drop the cash on all the kegging goodies, may as well look for cheap used fridge or chest freezer, and a temp controller.
but again, that's just my opinion.
