Josten hit it dead on. The extra cost is extremely appropriate for the jump in quality for the frame itself. The screen is not different, but if you look at their website it shows how the Criterion screen eliminates shadowing and helps to improve tension on the screen while providing a larger masking area (width) to the screen. Moreso, it is just a wider, heavier, better screen frame. Heavier may not matter much, but it supports the screen material in a more structurally sound manner which is ideal.
Better than the Precision, not to be confused with 'MUCH' better.
