I sell both models in my store. I sell very few PSR1500's compared to the PA50. Because the PSR1500 doesn't have the Mega Guitar sounds and the PA50 has such good unplugged typed styles, the Korg always gets the longer look from customers in my store and almost always it goes home with a customer over the 1500. Personally, I like the Korg better but comparing it to the PSR3000, I would find this a harder decision in choosing.
