What pedal would suit me?

im looking for an overdrive pedal and the pedals ive been looking at are zvex sho and box of rock and a fulltone ocd, my amp is an orange rocker 30 combo and i play a fender telecaster, can any one suggest one or if you have any other pedals what you think may be good, the music i play is realy indie rock like the cribs the strokes we are scientists libertines etc any help would be fantastic
