Problem is that the good 88 keybeds most of the time dont fit your pricing...
I would go for a casio..
Casio px-5s adds atleast some programable knobs and sliders..
And look into the studiologic line.. the 88 studio version is 13kg, the grand version 20mkg
Or even a nord stage used.. they are under that weight and build like a truck with good keybed
Also the nektar impact has 88 keys and a comtroller interface comparable to the code 61
However while it has a good keybed, it doesnt mimic a piano that much
Its middel of the road between piano and synth
So try before you buy
I domt know about the Roland rd2000, what does it weight?
Its an incredible master key
So are the kronos and the montage
All depends on what you expect from the keybed and what you want on your comtroll interface...
