Been looking to grab an ElectroLuminescence Casio for a while, as they are discontinuing EL in favour of LEDs, especially for the cheaper models.
Not the lowest price ever ($35 on Feb 2021), but near equal lowest in the last year at Amazon. Sold by Amazon AU, so expect it to be authentic, not sure if I would trust others with the number of fakes around.
