I was recently looking for a new screen for my Ryko AMTT. Every price I found seemed like a lot for a small black and white screen. I ended up finding a company who used to make similar screens. They discontinued that particular screen and are selling their remaining inventory at $10 a screen. I installed it and it worked perfectly. They were also very fast at shipping and very helpful in answering my questions. If anyone is looking for a new screen or a spare for their AMTT I would definitely recommend checking them out. Also, just to be clear, I am not associated with them in any way other than being a very happy customer
