Yup the Gotoh's are the goodies - they are a top lock so they don't have the big heavy thumbwheels on the back. The new 510s are very sexy with nice smooth lines and an 18:1 ratio:

The pic is of the 6-in-line, but they do also make them in a 3-a-side.
Only thing that might differ from the stock is the position of the screw. If yours are straight out at the bottom of the tuner, you might want to try a set of the Planet Waves:

Also 18:1 ratio and cut the end off the string automatically.
