Tyga do good screens and they are really cheap, i got some for my MC18 and one for a MC21. As they are so cheap even if you get charged VAT the percentage is nothing. When i got mine i wasnt charged any import tax etc.

I think Andy at NSR-world has a big order with tyga right now, PM him and see if he can order you one. He might be able to save you some money. Ive got a couple of things ordered with him right now.
