I'm always looking at for Sovereign's that people are selling.This is probably the best way to find Sovereign accessories.Example last week I bought a Sovereign off of Ebay with a Blackburn Night Hawk 180 meter that just needed a switch installed to fire up the night light.By the way the Night Hawk is on par(or even better) than the Sunray but will blank out in extreme heat and sunlight.Got an older S-1 these can be cut down smaller than the newer ones because of the wired connectors used.
