Paul,
Price difference is a lot in Holland (what I found till now though)
If I was in usa I would go to George as well.
I am in Holland so I buy the keyboard at my local dealer (who I know + 20 years) and I even don't mind he is a bit more expensive,
as online stores, because he gives an excellent service.

Solton:
X1+ HD dfl 6995,--
Harmonizer (us 175,--) so +/- " 395,--
(I did'nt ask Harmonizer so +/-)
dfl 7390,--

GEM WK 8-HD dfl 5295,--

In usdlr 970,-- (dfl 2095,--) more for the Solton X-I

But I did not hear the Solton Keyboard yet so I am convinced by all of you I have to hear it, so will go out tomorrow and let you know what I think!
Note:
I do use external gear for amplifying so the quality of internal amp/speakers are no issue for me.
Secondly I want a keyboard which sounds good but totally different as my Roland G 800, not
a keyboard with more of the same!
Thanks to all of you on this bbs, I think it's great!
Fred
