Bespeco Apollo looks very neat and has a lot of accessories to make it even better.
Another sturdy two-tier keyboard stand that allows space for MIDI foot controllers and various pedals - I guess Quik Lok Z-726 (or Z-726L for very wide keyboard) is very good starting point. We can build a complete mobile stage/studio keyboard station by adding following accessories to the Z-726 stand:
2 Z-731 shelfs (for speakers/monitors)
Z-732 music stand
X-728 telescopic mic boom
ZM-99 caster kit (for mobility, with locks)
The following picture is an interesting example of setup (without casters and speaker shelves):
