Airturn is certainly worth to look at. But don‘t buy anything older than the BT500 series. They are plastic but have the right type of clicks switches.
The IK BlueBoard also works well for me. It sends midi commands which I find quite appealing. The rubber switches don‘t feel that good.
I would not buy any pedals that emulate a keyboard like the IK BlueTurn or most of the lesser know brands page turners.
