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 :)
