Option 1, LMS used to sell a 3 piece one way back in the day, but finding one might take a few years and I've heard the fitment was sub-par.
Option 2, like you said is the Ford Taurus wing. It doesn't "hug the hump" well but I've seen more of those used.
Option 3 is to make your own, like Jason did with his. He took a second truck lid, cut the skin from the hump and "massaged it" on the his boot lid.
Personally I like not having one, too many nice lines on the car. But to each their own.
