Good sturdy basic stand
The IQ-1000 isn't going to be as rock solid as say a QuikLok heavy stand -- but it's pretty good.
I volunteer teach at a girls' rock camp program, keyboards -- most of the girls have never touched a keyboard. So I teach them things one can do immediately -- like B3-style pushes, glisses, clusters (I play B3 and synths), and holding things down til heat death of universe. We've gone through lots of keyboard stands! and the IQ-1000 has out-lasted all the others. Girls rock camp is rougher on gear, than any gigging situation! every day, the gear gets moved twice, by volunteers.
If you do a gliss, a push (my term, a gliss with a cluster of notes moving at once), in a B3-style, if you push parallel to the keyboard, you will minimize tending to push the keyboard off the stand (if you push away from your body, perpendicular to keyboard, obviously you'll tend to push keyboard off stand). I'm a very serious longtime B3 player whose style includes lots of roars, pushes, clusters.
One very good feature of the IQ-1000 is, you set the height you want, once, and thereafter it opens easily and automatically to that height. This is GREAT for the girls, the younger ones especially have trouble manipulating pull knobs, so we just set it and leave it be.
You have to make sure the "stabilizing end caps" are adjusted to best fit your situation -- sometimes they're rotated to a position that makes it rock, just rotate them a bit to stabilize.
