Here you can get one of the most used holders with the top page turners.

The Manos holder is exactly the same as The Gig Easy except the brand name. But, the Gig Easy site is unsecure and can't be accessed anymore.

Sometimes you can get B stock on airturn AND if you sign up for their newsletter and wait a little bit they will send you extra discounts.
