Locks

i'm looking for a mini d lock in addition to my kryptonite lock. So i don't want to fork out on an evo, especially as i think it would be better to have two makes of lock. So is thereany decent (but cheap) mini ds out there as an alternative to the evolution and that palmy lock?
Any help much appreciated, thanks

The onguard pitbull mini u might be good. It's got a double locking mechanism like the bigger krypto's have got which the evo doesnt
