Spector Bridge

Is there anyone that makes a bridge that will be a direct replacement for the recessed bridge (5 string) that Spector uses? It is a pain in the butt setting the intonation. I know that it is promoted as all of that but it is not the most friendly to adjust. Just thought I would see if there is an alternative, the fact that the body is routed out and the bridge placed in the cavity is unique and may be limiting any other. Thanks....Dave
