What TimT said: The $20 capper from your local store is fine. But it'll take an hour or so to fill all the bottles and get caps on.

I started kegging a couple of months ago, and it is really all of that and a bag of chips. I spend a few minutes transferring beer into the keg, then I carbonate based on physics instead of guessing. And if I do physics wrong, I can adjust to get it right afterwards -- no more flat beer or bottle-bombs.

But yeah, I used the big red capper like TimT pointed out for my first 4 full years of brewing, and it works great.
