Just be aware that the Apex stands are pretty hopeless for positioning pedals, apart from that they are very good.
I currently use a V-Stand(ultimate) with a Kurz pc1se on the bottom and a Tyros on the top with the shelf attachment, although I only use the shelf (for charts) when playing in piano only gigs.IE no Tyros.
FWIW The V-Stands look really cool, as do the Apex and both are far classier imo than an X- stand!!
Cheers
