Onguard BruteMini and a Krypto cable. The only complaint is that the key for the brute mini is ****ing huge (like the black plastic part at the end that hooks to the key ring) and jams up the flow of my keychain. Better than losing a bike, I guess.

Last I checked (week ago, maybe), the BruteMinis were on sale at Nashbar for like 25, that's when I got mine.
