I have a blackboard in my home office. I was quite surprised to find that a lot of them are available on e-bay and that they are quite cheap: I think, what happens is that, when schools get rid of them, teachers will sometimes take one home for their kids. Then, when the kids grow out of it, the blackboard ends up on e-bay. So, when I moved places, I used the opportunity that I already had a moving van rented and picked one up from someone selling one who was quite nearby, paying €50 for it. When I opened it, I realized that it had chalky deposits all over it that didn't go away with normal cleaning products. So I had to use a brush-bit for a power drill to scrub it clean. Then I found that I only have dry walls with hollow spaces beneath that can't carry the load (it weighs maybe around 100kg), so I made a technical drawing specifying a stand and went on etsy to look for a metal-worker who could make me that stand. All-in-all, it was just laying in a corner in my office for about a year until I finally finished the project of setting it up. So, it ended up being a lot more hassle than I thought it would be, but now I'm quite happy that I have it.
