Where can i get a good quality dual snorkel scoop?

thanks 72demon 340 for the info...im going to give them a call today and ask them if the scoop is functional and if it will fit the contour of the hood on my scamp (raised area in the middle)...its listed for a 70-72 duster which is the same hood, but i just want to make sure...anybody tried this PG classic scoop yet out of curiousity? i cant understand why the twin snorkel style is sooo expensive compared to other styles, but oh well
