HELP Wilh. Steinberg IQ77

[alexdxb]

Hi Everyone, sorry about my English it's not my first language and maybe I have some grammar mistakes, as I said on my previous post! I'm searching for a grand piano, a dealer sent me an email from US offering me a Wilh. Streinberg IQ77 I saw in some websites that is a handmade German piano very fine instrument in this case it's a 2004 it's a 5'8" asking price $18.500
My questions are:
Has anyone here played this piano?
How's comparing to a Yamaha C3 or Kawai G30 I guess both 6'1"?
It's the price reasonable?
Been an European made piano would it be ok to bring to this hot weather of Dubai or should I consider the humidifier (also has anyone here used them)
Sorry for so many questions
As I said I'm so confused I need help
