I use the
Quik Lok M-92 stand. It is quite sturdy, has great leg room unlike the 'X' style stands and folds up fast.
For multiple keyboards, the Quik Lok M-92 is probably the best of the lot, especially if you plan on using bass pedals.
I use a double brace X-stand (Quik Lok) for my Tyros4...it is rock solid, and very easy to set up/break down.
