In my experience the best v-brakes were the Shimano XTR, XT or LX models which featured parallel push brake arms. The way they kept the pads parallel to the rims made for really good stopping power while giving you better modulation. They were popular in the late 90's early noughties, so if you search the bay you should be able to find some.
Edit: Here are the sets I mentioned, I'd go for the XT ones...
So bottom line is, any v brakes with good quality pads (as I always do anyway) set up correctly, you can't go wrong?
