Hi Fella
The L7B stand, from Yamaha is a very strong sturdy stand. However it is not adjustable for height, and so be aware of that. For most people, sitting at a keyboard it would be fine, but if you're gigging or a stand up player it's not easily as easily transportable either.One size does NOT fit all.
Don't buy a Scissor or X frame stands either. Although easy to transport and set up, they are not stable enough, and you can't get your knees under them!
I use a Stagg MXS-A1 stand myself. See their website. Stagg also make microphone booms, tablet stands, and other accessories to fi this stand.
Whatever you buy, enjoy.
Keith.
