I'm using the ground glass with my TK 45S. I would prefer a screen that is unif ormly brighter, and easier to focus. I saw the Beattie- much brighter, but I did n't love it. The Bos is too delicate for me(in terms of temperature tolerence). Is the best advice just to stick with the original ground glass? What is your e xperince and advice. Thanks.
