We tried this at our work, where we use whiteboards extensively. I am not a fan. You spend a lot of time trying to make them clean over a 2 year period. It's annoying to be constantly replacing them.

We have moved on to http://www.ideapaint.com/products/ideapaint and are really happy with the result. Cheaper then traditional white boards and better then the Showerboards. The room we tested it in currently has had it up for a year and still works well and easily erasing things that have been up for a month.

IdeaPaint does not compare. It more reminiscent of a white truck bed liner than a writing slate, even when installed by their contractors. It gets the job done for silly after-hours doodles but its simply not as precise as a real glossy whiteboard when it comes to legibility and ease to clean.

All of our old traditional whiteboards mysteriously appeared after a few weeks.

If you are going cheap, my lower bound is ideapaint, but I agree there is a reason good whiteboards are still sold :)

I was looking at the http://masschallenge.org/ office space where they use ideapaint. They paint is very glossy with a bad glare from over head lighting. I couldn't see what was written on the ideapaint from the glare. It would probably be great with some softer overhead lighting.
