I have a couple of the stands that Sundew shows, one for my SP88X stage piano in the living room, and another for playing gigs with my K2661 synth. Excellent stand - nothing in the way of the legs, pedals can be reached.
One suggestion: I bought acouple of pieces of black felt large enough to cover the "table" parts of the stand, and cemented them firmly in place. Keeps the keyboard from being scratched up on the botton, and makes it less likely that it will slide around on the stand.
For a two level stand, I use the OnStage model like this: http://www.zzounds.com/item--MUPKS7365EJ
Does an excellent job holding an 88 key weighted keyboard on the lower level and a 61 key unweighted keyboard on the upper level. The horizontal parts below the keyboard are far enough back that I can place pedals in front of them, and the unit is very sturdy and stable. I use this one in my studio.
I like a keyboard that sits firmly in place and doesnt jiggle about. Never found an X stand that gave me good results.
