It seems that Yamaha and Roland protect their US dealers and Korg,Ketron and perhaps Technics do not. With Technics,who knows, as most of their dealers really do have an obscene markup.Ketron has such a small US distribution that it is hard to tell.
I suspect that with Korg it is the US dealers who are the victims here. It is not your local dealer simply deciding to make a large profit that accounts for the difference between the pa80 and the psr2k here in the states. It is the difference in wholesale cost that US dealers pay more than Synthplanet pays for the same merchandise.I think that if you compare US prices that you will find that SD1,KN6500,etc. will cost close to 3x the psr2k. For that much, I would buy from Synthplanet and to hell with the warranty!
But if your real final cost is within say 25% or so, you may find that warranty and local support from a GOOD dealer is worth paying the difference. By the way,this is not an argument,I'm just trying to give you more of a complete picture. If you do buy from Synthplanet, please let us know how it turns out. I hope you love your new keyboard.
