KS-1001 : Sturdy enough, great build quality

I can't believe I found a keyboard stand that's so cheap and solid at the same time. This level of quality is usually indicative of a high price, not in this case.

The locking mechanism is pretty standard, with a protruding bolt that fixes the legs at predetermined heights. All four legs are rubberised on both sides (8 contact points in total), providing excellent grip and stability.

At lower heights, it's not really that good for 49-ers and below, unless you somehow have a really long keyboard with tons of padding around keys. Of course, this is because the stand has to be spread further apart at lower heights: it can either be short and wide or tall and narrow. I'm using it with an Alesis V49 keyboard and for my use it's pretty close -- not uncomfortable, but just a few centimetres shy of being perfect.

It's reasonably compact when folded, but don't expect miracles.

In summary, absolutely get this stand if you're on a budget and have a 61 keys and above keyboard.
