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 evo isn't that expensive, it's about £25-30 mate, there's nowt wrong with that lock.
