I was looking for a stand with welded legs and all I could find were this one, the Proline, and probably the Hercules. I would not recommend any of the stands that you have to put together with bolts. Welded legs are much more accident/abuse-friendly. What sold me on this model over the Proline and Hercules is the offset attachment of the crossbeams on the legs. There is much more room for your legs. My PCR-500 fits on this perfectly and the height adjustment has plenty of settings to suit standing or sitting. I haven't had any trouble with my keyboard bouncing around.
