They're rated for loads up to 100lbs, and they're plenty tough enough to hold up a full-sized MIDI controller. They're stiff enough too.
If you're worried, though, you can double them up (two on each side). Now, you're at $30. Typically, when you double up, the load-baring capacity more than doubles.
I have a planer, but I didn't use it at all in this project.
Might be regional. US has a ton of land and resources, so maybe wood is cheaper here. You're pricing in Euros, and Europe is a bit more densely populated.
