Digital piano- purchase advice

[chessman]

I want to buy digital piano in unpcoming weeks, so I thought it would be good idea to ask on this forum about it. At internet you can mostly get opinion that best digital pianos are made by yamaha BUT when I asked around outside internet most people said that Roland is the best. Not many Yamahas in my city to test but I've tested some(clp 430 and something from "p" series),then I tested Roland hp 503 and well... there was HUGE diffrence, I mean Roland is totally destroying Yamaha clp 430. So what do you think? My budget for now is max Roland hp 506 which I'm aiming for now. But I didn't have oportunity to test higher Yamahas models. From what information I could gather it seems that I would have to give almost twice as much for equal sound in Yahama. Is it true?
As I said I myself have tested some digital pianos but not early enough, I've checked also Casio, Kawai and some others but nothing compared to the Roland I'd pleasure to play.

Edit: I made this topic in wrong place, could you please remove it?
